The next full Moon is the Wolf Moon; the Ice or Old Moon; the Moon after Yule; the start of Prayag Kumbh Mela; Shakambhari Purnima; Paush Purnima; the Thiruvathira, Thiruvathirai, or Arudhra Darisanam festival Moon; and Duruthu Poya.

The next full Moon will be Monday evening, Jan. 13, 2025, appearing opposite the Sun (in Earth-based longitude) at 5:27 p.m. EST. This will be Tuesday from the South Africa and Eastern European time zones eastward across the remainder of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning. On the night of the full Moon, for most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of the planet Mars.

The Maine Farmers’ Almanac began publishing Native American names for full Moons in the 1930s. Over time these names have become widely known and used. According to this almanac, as the full Moon in January this is the Wolf Moon, from the packs of wolves heard howling outside the villages amid the cold and deep snows of winter.

European names for this Moon include the Ice Moon, the Old Moon, and (as the full Moon after the winter solstice) the Moon after Yule. Yule was a three to 12-day festival near the winter solstice in pre-Christian Europe. In the tenth century King Haakon I associated Yule with Christmas as part of the Christianization of Norway, and this association spread throughout Europe. The exact timing of this pre-Christian celebration is unclear. Some sources now associate Yule with the 12 days of Christmas, so that the Moon after Yule is after Twelfth Night on January 6. Other sources suggest that Yule is an old name for the month of January, so the Moon after Yule is in February. In the absence of more reliable historic information, I’m going with the full Moon after the winter solstice as the Moon after Yule.

This full Moon corresponds with the start of the 44-day festival Prayag Kumbh Mela, also known as Maha Kumbh. This Hindu pilgrimage and festival is held every 12 years in the Indian city of Prayagraj at the confluence of three rivers, the Ganges, the Yamuna, and the mythical Sarasvati. It is expected to draw around 400 million visitors. Similar Kumbh celebrations are held approximately every 12 years at the convergence of three rivers in three other Indian cities, Nashik (upcoming in 2027), Ujjain (in 2028), and Haridwar (in 2033).

In the Hindu calendar, this full Moon is Shakambhari Purnima, the last day in the 8-day Shakambari Navratri holiday that celebrates the goddess Shakambhari. In the Purnimanta tradition that ends months on the full Moon day, this full Moon is Paush Purnima, the last day of the Hindu month of Paush. The day after Paush Purnima is the start of the month of Magha, a period of austerity. Bathing in the holy waters of India is an important activity for both Shakambari Navratri and Magha.

This full Moon corresponds with the Thiruvathira, Thiruvathirai, or Arudhra Darisanam festival, celebrated by Hindus in the Indian states of Kerala and Tamil Nadu.

For the Buddhists of Sri Lanka, this is Duruthu Poya, which commemorates Siddhartha Gautama Buddha’s first visit to Sri Lanka.

In many lunar and lunisolar calendars the months change with the new Moon and full Moons fall in the middle of the lunar month. This full Moon is in the middle of the 12th and final month of the Chinese Year of the Rabbit. The new Moon on January 29 will be Chinese New Year, the start of the Year of the Snake. This full Moon is in the middle of Tevet in the Hebrew calendar and Rajab, the seventh month of the Islamic calendar. Rajab is one of the four sacred months in which warfare and fighting are forbidden.

As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon. Take care in the cold weather and take advantage of these early sunsets to enjoy and share the wonders of the night sky. And avoid starting any wars.

Here are the other celestial events between now and the full Moon after next, with times and angles based on the location of NASA Headquarters in Washington, D.C.:

As winter continues in the Northern Hemisphere, the daily periods of sunlight continue to lengthen. Our 24-hour clock is based on the average length of a day with the solar days near the solstices longer than those near the equinoxes. For Washington, D.C. and similar latitudes (I’ve not checked for other areas) the latest sunrise of the year (ignoring Daylight Saving Time) occurred on January 4. Monday, January 13 (the day of the full Moon), morning twilight will begin at 6:24 a.m. EST, sunrise will be at 7:26 a.m., solar noon will be at 12:17 p.m. when the Sun will reach its maximum altitude of 29.8 degrees, sunset will be at 5:08 p.m., and evening twilight will end at 6:11 p.m. By Wednesday, February 12 (the day of the full Moon after next), morning twilight will begin at 6:04 a.m., sunrise will be at 7:03 a.m., solar noon will be at 12:23 p.m. when the Sun will reach its maximum altitude of 37.7 degrees, sunset will be at 5:43 p.m., and evening twilight will end at 6:41 p.m.

This should be a good time for planet watching, especially with a backyard telescope. Venus, Jupiter, Mars, Saturn, and Uranus will all be in the evening sky. Brightest will be Venus, appearing in the southwestern sky. With a telescope you should be able to see it shift from half-full to a 29% illuminated crescent during this lunar cycle as it brightens and moves closer to the Earth.

Venus will reach its brightest for the year just after the full Moon after next. Second in brightness will be Jupiter in the eastern sky. With a telescope you should be able to see Jupiter’s four bright moons, Ganymede, Callisto, Europa, and Io, noticeably shifting positions in the course of an evening. Jupiter was at its closest and brightest in early December. Third in brightness will be Mars low in the east-northeastern sky. Mars will be at its closest and brightest for the year a few days after this full Moon. Fourth in brightness will be Saturn, appearing near Venus in the southwestern sky. With a telescope you should be able to see Saturn’s bright moon Titan and maybe its rings. The rings are appearing very thin and will be edge-on to the Earth in March 2025. We won’t get the “classic” view of Saturn showing off its rings until 2026. Saturn was at its closest and brightest in early September and will appear its closest to Venus (2.2 degrees apart) the evening of January 18. Fifth in brightness and technically bright enough to see without a telescope (if you are in a very dark location and your eyesight is better than mine) will be Uranus high in the southeastern sky. Uranus was at its closest and brightest in mid-November.

During this lunar cycle these planets will be rotating westward around the pole star Polaris (with Venus shifting more slowly) making them easier to see earlier in the evening, and friendlier for backyard stargazing, especially if you have young ones with earlier bedtimes.

Comets

As mentioned in my last posting, the sungrazing comet C/2024 G3 (ATLAS) will be passing very near the Sun on January 13. There is a chance that this comet will break up and vanish from view as it approaches the Sun, much as comet C/2024 S1 (ATLAS) did in October. In addition, its visual magnitude might not be bright enough to see in the daytime due to the glow of the nearby Sun. If it does not break up and is bright enough, Northern Hemisphere viewers will have the best viewing near its closest approach. For the Washington, D.C. area, it could be brightest the evening of January 12 before it sets on the southwestern horizon. You will need to find a distant object to block direct sunlight so you can safely look about 5 degrees to the upper right of the Sun. If the horizon is very clear, your best chance might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. Southern Hemisphere viewers will have the best viewing after closest approach, immediately after sunset from mid-January on (dimming each evening as it moves away from the Sun and the Earth). You may need binoculars or a telescope to see it, although comets are hard to predict.

Meteor Showers

Two minor meteor showers, the γ-Ursae Minorids (404 GUM) and α-Centaurids (102 ACE), will peak during this lunar cycle. The light of the waning Moon will interfere with the γ-Ursae Minorids peak on January 18. The α-Centaurids, only visible from the Southern Hemisphere, are expected to peak on February 8. In recent years the average peak has been 6 visible meteors per hour (under ideal conditions), although this shower showed bursts of 20 to 30 meteors per hour in 1974 and 1980. The best viewing conditions will likely be after the waxing gibbous Moon sets in the early mornings around the peak.

Evening Sky Highlights

On the evening of Monday, Jan. 13, 2025 (the evening of the full Moon), as twilight ends (at 6:11 p.m. EST), the rising Moon will be 13 degrees above the east-northeastern horizon with the bright planet Mars (the third brightest planet) 2 degrees to the lower left and the bright star Pollux (the brighter of the twin stars in the constellation Gemini, the twins) 3 degrees to the upper left of the Moon. The brightest planet visible will be Venus at 29 degrees above the southwestern horizon, with the planet Saturn (fourth brightest) 6 degrees to the upper left of Venus. The second brightest planet, Jupiter, will be 47 degrees above the eastern horizon. The bright star closest to overhead will be Capella at 50 degrees above the east-northeastern horizon. Capella is the 6th brightest star in our night sky and the brightest star in the constellation Auriga (the charioteer). Although we see Capella as a single star it is actually four stars (two pairs of stars orbiting each other). Capella is about 43 light years from us.

As this lunar cycle progresses, the planets and the background of stars will appear to rotate westward around the pole star Polaris each evening, with Venus initially shifting the other direction. Mars will be at its closest and brightest on January 15. Venus and Saturn will appear closest to each other on January 18. Mars and Pollux will appear nearest each other on January 22 and 23. Venus will appear at its highest above the horizon (as twilight ends) on January 27, after which it will start shifting toward the horizon again. Jupiter and Aldebaran will appear at their closest on January 31. The waxing Moon will pass by Saturn on January 31; Venus on February 1; the Pleiades star cluster on February 5; and Mars and Pollux on February 10.

By the evening of Wednesday, February 12 (the evening of the full Moon after next), as twilight ends (at 6:41 p.m. EST), the rising Moon will be 7 degrees above the east-northeastern horizon with the bright star Regulus 2 degrees to the right. The brightest planet in the sky will be Venus at 28 degrees above the west-southwestern horizon, appearing as a crescent through a telescope. Next in brightness will be Jupiter at 71 degrees above the south-southeastern horizon. Third in brightness will be Mars at 48 degrees above the eastern horizon. Saturn will be 11 degrees above the west-southwestern horizon. Uranus, on the edge of what is visible under extremely clear, dark skies, will be 68 degrees above the south-southwestern horizon. The bright star closest to overhead will still be Capella at 75 degrees above the northeastern horizon.

Also high in the sky will be the constellation Orion, easily identifiable because of the three stars that form Orion’s Belt. This time of year, we see many bright stars in the sky at evening twilight, with bright stars scattered from the south-southeast toward the northwest. We see more stars in this direction because we are looking toward the Local Arm of our home galaxy (also called the Orion Arm, Orion-Cygnus Arm, or Orion Bridge). This arm is about 3,500 light years across and 10,000 light years long. Some of the bright stars we see from this arm are the three stars of Orion’s Belt, as well as Rigel (860 light years from Earth), Betelgeuse (548 light years), Polaris (about 400 light years), and Deneb (about 2,600 light years).

Facing toward the south from the northern hemisphere, to the upper left of Orion’s Belt is the bright star Betelgeuse (be careful not to say this name three times). About the same distance to the lower right is the bright star Rigel. Orion’s belt appears to point down and to the left about seven belt lengths to the bright star Sirius, the brightest star in the night sky. Below Sirius is the bright star Adara. To the upper right of Orion’s Belt (at about the same distance from Orion as Sirius) is the bright star Aldebaran. Nearly overhead is the bright star Capella. To the left (east) of Betelgeuse is the bright star Procyon. The two stars above Procyon are Castor and Pollux, the twin stars of the constellation Gemini (Pollux is the brighter of the two). The bright star Regulus appears farther to the left (east) of Pollux near the eastern horizon. Very few places on the East Coast are dark enough to see the Milky Way (our home galaxy), but if you could see it, it would appear to stretch overhead from the southeast to the northwest. Since we are seeing our galaxy from the inside, the combined light from its 100 billion to 400 billion stars make it appear as a band surrounding the Earth.

Morning Sky Highlights

On the morning of Monday, Jan. 13, 2025 (the morning of the full Moon), as twilight begins (at 6:23 a.m. EST), the setting full Moon will be 11 degrees above the west-northwestern horizon. This will be the last morning the planet Mercury will rise before morning twilight begins, although it will be bright enough to see in the glow of dawn after it rises for another week or so. This will leave Mars at 18 degrees above the west-northwestern horizon as the only planet in the sky. The bright star appearing closest to overhead will be Arcturus at 69 degrees above the south-southeastern horizon. Arcturus is the brightest star in the constellation Boötes (the herdsman or plowman) and the 4th brightest star in our night sky. It is 36.7 light years from us. While it has about the same mass as our Sun, it is about 2.6 billion years older and has used up its core hydrogen, becoming a red giant 25 times the size and 170 times the brightness of our Sun. One way to identify Arcturus in the night sky is to start at the Big Dipper, then follow the arc of the dipper’s handle as it “arcs toward Arcturus.”

As this lunar cycle progresses Mars and the background of stars will appear to rotate westward around the pole star Polaris by about 1 degree each morning. The waning Moon will appear near Mars and Pollux on January 13 and 14, Regulus on January 16, Spica on January 21, Antares on January 24 and 25, and (rising after morning twilight begins) Mercury on January 28. January 22 will be the last morning the planet Mercury will be above the horizon 30 minutes before sunrise. Mars and Pollux will be near their closest to each other the morning of January 23. February 4 will be the last morning the planet Mars will be above the northwestern horizon as morning twilight begins. The waxing Moon will appear near Pollux on February 9 (setting before twilight begins) and 10.

By the morning of Wednesday, February 12 (the morning of the full Moon after next), as twilight begins (at 6:04 a.m. EST), the setting full Moon will be 13 degrees above the western horizon. No planets will appear in the sky. The bright star appearing closest to overhead will still be Arcturus at 65 degrees above the southeastern horizon.

Detailed Daily Guide

Here is a day-by-day listing of celestial events between now and the full Moon on Feb. 12, 2025. The times and angles are based on the location of NASA Headquarters in Washington, D.C., and some of these details may differ for where you are (I use parentheses to indicate times specific to the D.C. area). If your latitude is significantly different than 39 degrees north (and especially for my Southern Hemisphere readers), I recommend using an astronomy app set for your location or a star-watching guide from a local observatory, news outlet, or astronomy club.

Tuesday evening, January 7 At 7:07 p.m. EST, the Moon will be at perigee, its closest to the Earth for this orbit.

Thursday evening, January 9 The waxing gibbous Moon will pass in front of the Pleiades star cluster. This may be viewed best with binoculars, as the brightness of the Moon will make it hard to see the stars in this star cluster. As evening twilight ends at 6:07 p.m. EST, the Pleiades will appear 1 degree to the lower left of the full Moon. Over the next few hours, including as the Moon reaches its highest for the night at 8:37 p.m., the Moon will pass in front of the Pleiades, blocking many of these stars from view. By about midnight the Pleiades will appear about 1 degree below the Moon, and the Moon and the Pleiades will separate as Friday morning progresses.

Also on Thursday night, January 9, the planet Venus will reach its greatest angular separation from the Sun as seen from the Earth for this apparition (called greatest elongation). Because the angle between the line from the Sun to Venus and the line of the horizon changes with the seasons, the date when Venus and the Sun appear farthest apart as seen from Earth is not always the same as when it appears highest above the west-southwestern horizon as evening twilight ends, which occurs on January 27.

Friday evening, January 10 The bright planet Jupiter will appear near the waxing gibbous Moon. As evening twilight ends at 6:08 p.m. EST, Jupiter will be 5 degrees to the lower right. As the Moon reaches its highest for the night at 9:37 p.m., Jupiter will be 6 degrees below the Moon. The pair will continue to separate until Jupiter sets Saturday morning at 4:45 a.m.

Sunday afternoon, January 12 There is a slight chance that the sungrazing comet, C/2024 G3 (ATLAS) might be visible near the setting Sun. Most likely, this comet will not be bright enough to see in the daytime or will break up and vanish from view like comet C/2024 S1 (ATLAS) did in October. The odds are low, but if the sky is clear, find an object to block direct sunlight (the farther away the object the better) so you can safely look about 5 degrees to the upper right of the Sun. If the west-southwestern horizon is clear, your best chance might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. This will only be visible from the Northern Hemisphere. Southern Hemisphere viewers may be able to see this comet from mid-January on immediately after sunset (dimming each evening as it moves away from us).

Monday morning, January 13 This is the morning of the full Moon. It will be the last morning Mercury will rise before morning twilight begins, although it will be bright enough to see in the glow of dawn after it rises for another week or so.

The Moon will be full Monday evening at 5:27 p.m. EST. This will be on Tuesday from the South Africa and Eastern European time zones eastward across the rest of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning.

On Monday night the full Moon will appear near and pass in front of the bright planet Mars, with the bright star Pollux above the pair. As evening twilight ends at 6:11 p.m. EST, the three will form a triangle, with Mars 2 degrees to the lower left and Pollux 3 degrees to the upper left of the Moon. For most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of Mars. Times will vary for other locations, but for NASA Headquarters in Washington, D.C., Mars will vanish behind the bottom of the Moon at about 9:16 p.m. and reappear from behind the upper right of the Moon at about 10:31 p.m. By the time the Moon reaches its highest for the night early on Tuesday morning at 12:37 a.m., Mars will be 1 degree to the right of the Moon and Pollux 5 degrees to the upper right. As morning twilight begins at 6:23 a.m., Mars will be 4 degrees and Pollux 8 degrees to the lower right of the Moon.

Wednesday night January 15 The planet Mars will be at opposition, so called because it will be opposite the Earth from the Sun, effectively a “full” Mars. Near opposition Mars will be at its closest and brightest for the year. On Wednesday night, as evening twilight ends at 6:13 p.m. EST, Mars will be 14 degrees above the east-northeastern horizon. Mars will reach its highest in the sky early Thursday morning at 12:21 a.m., and will be 15 degrees above the west-northwestern horizon as morning twilight begins at 6:23 a.m. Only planets that orbit farther from the Sun than the Earth can be seen at opposition from the Earth.

Wednesday night into Thursday morning, January 15 to 16 The bright star Regulus will appear near the waning gibbous Moon. As Regulus rises on the east-northeastern horizon at 7:52 p.m. EST, it will be more than 8 degrees below the Moon. By the time the Moon reaches its highest for the night on Thursday morning at 2:17 a.m. Regulus will be 5.5 degrees to the lower left of the Moon. As morning twilight begins at 6:23 a.m. Regulus will be 4 degrees to the left of the Moon.

Saturday evening, January 18 Venus and Saturn will appear nearest to each other. As evening twilight ends at 6:15 p.m. EST, Venus will be 30 degrees above the southwestern horizon with Saturn 2.2 degrees to the lower left. Saturn will set first on the western horizon almost 3 hours later at 9:04 p.m.

Monday night, January 20 At 11:53 p.m. EST, the Moon will be at apogee, its farthest from the Earth for this orbit.

Tuesday morning, January 21 The bright star Spica will appear near the waning gibbous Moon. As the Moon rises on the east-southeastern horizon at 12:11 a.m. EST Spica will be 1 degree above the Moon. By the time the Moon reaches its highest for the night at 5:41 a.m., Spica will be 3.5 degrees to the upper right, with morning twilight beginning 40 minutes later at 6:21 a.m. For parts of Western Africa and the Atlantic Ocean the Moon will pass in front of Spica.

Tuesday afternoon, the waning Moon will appear half-full as it reaches its last quarter at 3:31 p.m. EST (when we can’t see it).

Wednesday morning, January 22 This will be the last morning Mercury will be above the horizon 30 minutes before sunrise, an approximation of the last morning it might be visible in the glow of dawn.

Throughout this lunar cycle, Mars and the bright star Pollux will appear near each other, with Wednesday night into Thursday morning and Thursday night into Friday morning (January 22, 23, and 24) the nights when they will be at their closest, 2.5 degrees apart. They will be up all night for both nights, with Mars at its highest on Wednesday night at 11:41 p.m. EST, and Thursday night at 11:36 p.m.

Friday morning, January 24 The bright star Antares will appear to the lower left of the waning crescent Moon. As Antares rises on the southeastern horizon at 3:54 a.m. EST, it will be 8 degrees from the Moon. By the time morning twilight begins less than 2.5 hours later at 6:19 a.m., Antares will be 6.5 degrees from the Moon. For part of the Indian Ocean the Moon will actually pass in front of Pollux.

Saturday morning, January 25 The Moon will have shifted to the other side of Antares. As the Moon rises at 4:20 a.m. EST, Antares will be 6 degrees to the upper right of the Moon. By the time morning twilight begins 2 hours later at 6:19 a.m., Antares will be 7 degrees from the Moon.

Monday evening, January 27 Venus will be at its highest above the west-southwestern horizon (31 degrees) as evening twilight ends at 6:25 p.m. EST, appearing as a 41% illuminated crescent through a telescope.

Wednesday morning, January 29 At 7:36 a.m. EST there will be a new Moon, when the Moon passes between the Earth and the Sun, and the Moon will not be visible from the Earth. The day of, or the day after, the New Moon marks the start of the new month for most lunisolar calendars. The first month of the Chinese calendar starts on Wednesday, January 29, making this Chinese New Year, the start of the Year of the Snake! Chinese New Year and related celebrations throughout much of Asia and in areas with significant Chinese populations celebrate the end of winter and start of spring. Traditional festivities start on the eve of Chinese New Year and continue until the Lantern Festival on the 15th day of the first lunar month.

Sundown on Wednesday, January 29 This marks the start of Shevat in the Hebrew calendar.

Sundown on Thursday, January 30 In the Islamic calendar, the months traditionally start with the first sighting of the waxing crescent Moon. Many Muslim communities now follow the Umm al-Qura Calendar of Saudi Arabia, which uses astronomical calculations to start months in a more predictable way. Using this calendar, sundown on Thursday, January 30, will probably mark the beginning of Shaʿbān, the eighth month of the Islamic year and the month before Ramadan.

Friday evening, January 31 Saturn will appear 4 degrees to the upper left of the waxing crescent Moon. The Moon will be 17 degrees above the west-southwestern horizon as evening twilight ends at 6:29 p.m. EST, and will set on the western horizon 99 minutes later at 8:08 p.m. For part of Asia the Moon will actually pass in front of Saturn.

Throughout this lunar cycle the bright star Aldebaran will appear below the bright planet Jupiter, with Friday, January 31 the evening they appear at their closest, about 5 degrees apart. As evening twilight ends at 6:29 p.m. EST, Jupiter will be 65 degrees above the southeastern horizon with Aldebaran to the lower right. Jupiter will reach its highest for the night, 73 degrees above the southern horizon at 8:01 p.m., with Aldebaran below Jupiter. As Aldebaran sets on the west-northwestern horizon almost 7 hours after that at 2:56 a.m. it will be to the lower left of the Moon.

Saturday evening, February 1 Venus will appear near the waxing crescent Moon. The Moon will be 30 degrees above the west-southwestern horizon as evening twilight ends at 6:30 p.m. EST, with Venus 2.5 degrees to the upper right. Venus will be 2.5 degrees to the lower right as it sets first on the western horizon 2.75 hours later at 9:15 p.m.

Saturday night, at 9:38 p.m. EST, the Moon will be at perigee, its closest to the Earth for this orbit.

Saturday also is Imbolc or Imbolg, and the next day (Sunday, February 2) is Candlemas or Groundhog’s Day. We currently divide the year into four seasons based upon the solstices and equinoxes, with spring starting on the vernal equinox. This approximates winter as the quarter of the year with the coldest temperatures. Much of pre-Christian northern Europe celebrated “cross-quarter days” halfway between the solstices and equinoxes, dividing the seasons on these days. Using this definition, winter was the quarter of the year with the shortest daily periods of daylight, and spring started on Imbolc (the middle of our winter).

The tradition in some European countries was to leave Christmas decorations up until February 1st, the eve of Candlemas, and it was considered bad luck to leave decorations up past this date. Robert Herrick (1591-1674) starts his poem “Ceremonies for Candlemas Eve” with “Down with the rosemary and bays, down with the mistletoe; Instead of holly, now up-raise the greener box (for show).”

We have a tradition in the United States that winter will end on Groundhog Day if the groundhog sees its shadow. If not, winter will last six weeks more (ending around the time of the spring equinox). Groundhog Day appears to tie back to European lore about whether or not badgers, wolves, or bears (instead of groundhogs) see their shadows. Many believe that these Groundhog Day and Candlemas traditions tie back to these earlier celebrations for the start of spring. It seems plausible to me that it was confusing to have two competing dates for the end of winter. Perhaps it was best to let a natural event such as an animal’s shadow decide which definition to use, rather than arguing with your neighbors for the next six weeks.

Tuesday morning, February 4 This will be the last morning Mars will be above the northwestern horizon as morning twilight begins.

Wednesday morning, February 5 The Moon will appear half-full as it reaches its first quarter at 3:02 a.m. EST (when we can’t see it).

Wednesday evening the waxing gibbous Moon will appear near the Pleiades star cluster. As evening twilight ends at 6:34 p.m. EST, this star cluster will be 5 degrees to the upper left of the Moon. The Pleiades will shift closer toward the Moon until the Moon sets on the west-northwestern horizon less than 8 hours later at 2:16 a.m. Some North American locations farther west will actually see the Moon pass in front of some of the stars in the Pleiades.

Sunday morning, February 9 Mars will appear to the upper left of the waxing gibbous Moon. In the early morning at about 2 a.m. EST, Mars will be 8 degrees from the Moon. By the time the Moon sets on the northwestern horizon at 5:58 a.m., Mars will have shifted to 6 degrees from the Moon. For parts of Asia and Northern Europe the Moon will pass in front of Mars.

Also Sunday morning, Mercury will be passing on the far side of the Sun as seen from the Earth, called superior conjunction. Because Mercury orbits inside of the orbit of Earth it will be shifting from the morning sky to the evening sky and will begin emerging from the glow of dusk on the west-southwestern horizon after about February 17 (depending upon viewing conditions).

Sunday evening into Monday morning, February 9 to 10 The waxing gibbous Moon will have shifted to the other side of Mars (having passed in front of Mars in the afternoon when we could not see them). As evening twilight ends at 6:38 p.m. EST, the Moon will be between Mars and the bright star Pollux, with Mars 3 degrees to the upper right and Pollux 3 degrees to the lower left. By the time the Moon reaches its highest for the night at 10:27 p.m., Mars will be 4.5 degrees to the right of the Moon and Pollux 2.5 degrees to the upper left of the Moon. Mars will set first on the northwestern horizon Monday morning at 5:44 a.m. just 22 minutes before morning twilight begins at 6:06 a.m.

Wednesday morning, February 12 The full Moon after next will be at 8:53 a.m. EST, with the bright star Regulus nearby. This will be on Thursday morning from Australian Central Time eastward to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Monday night into early Thursday evening.

      3 Min Read NASA Shares Final Contenders for Artemis II Moon Mascot Design Contest
      NASA is down to 25 finalists for the Artemis II zero gravity indicator set to fly with the mission’s crew around the Moon and back next year.

      Astronauts Reid Wiseman, Victor Glover, and Christina Koch of NASA, and CSA (Canadian Space Agency) astronaut Jeremy Hansen will soon select one of the finalist designs to join them inside the Orion spacecraft as their Moon mascot.

      “The Artemis II zero gravity indicator will be special for the crew,” said Reid Wiseman, Artemis II commander. “In a spacecraft filled with complex hardware to keep the crew alive in deep space, the indicator is a friendly and useful way to highlight the human element that is so critical to our exploration of the universe. Our crew is excited about these designs from across the world and we are looking forward to bringing the winner along for the ride.”

      A zero gravity indicator is a small plush item that typically rides with a crew to visually indicate when they are in space. For the first eight minutes after liftoff, the crew and their indicator nearby will still be pushed into their seats by gravity, and the force of the climb into space. When the main engines of the SLS (Space Launch System) rocket’s core stage cut off, gravity’s restraints are lifted, but the crew will still be strapped safely into their seats – their zero gravity indicator’s ability to float will provide proof that they’ve made it into space.

      Artemis II will mark the first time that the public has had a hand in creating the crew’s mascot.

      These designs – ideas spanning from Moon-related twists on Earthly creatures to creative visions of exploration and discovery – were selected from more than 2,600 submissions from over 50 countries, including from K-12 students. The finalists represent 10 countries including the United States, Canada, Colombia, Finland, France, Germany, Japan, Peru, Singapore, and Wales.

Creators were asked to submit ideas representing the significance of Artemis, the mission, or exploration and discovery, and to meet specific size and materials requirements. Crowdsourcing company Freelancer facilitated the contest on NASA’s behalf though the NASA Tournament Lab, managed by the agency’s Space Technology Mission Directorate.

      Once the crew has selected a final design, NASA’s Thermal Blanket Lab will fabricate it for flight. The indicator will be tethered inside Orion before launch.

      The approximately 10-day mission is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.

      Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s Psyche captured images of Earth and our Moon from about 180 million miles (290 kilometers) away in July 2025, as it calibrated its imager instrument. When choosing targets for the imager testing, scientists look for bodies that shine with reflected sunlight, just as the asteroid Psyche does.NASA/JPL-Caltech/ASU Headed for a metal-rich asteroid of the same name, the Psyche spacecraft successfully calibrated its cameras by looking homeward.
      On schedule for its 2029 arrival at the asteroid Psyche, NASA’s Psyche spacecraft recently looked back toward home and captured images of Earth and our Moon from about 180 million miles (290 million kilometers) away. The images were obtained during one of the mission team’s periodic checkouts of the spacecraft’s science instruments.
      On July 20 and July 23, the spacecraft’s twin cameras captured multiple long-exposure (up to 10-second) pictures of the two bodies, which appear as dots sparkling with reflected sunlight amid a starfield in the constellation Aries.
      Learn more about the multispectral imager aboard Psyche that will use a pair of identical cameras with filters and telescopic lenses to photograph the surface of the asteroid in different wavelengths of light. NASA/JPL-Caltech/ASU The Psyche multispectral imager instrument comprises a pair of identical cameras equipped with filters and telescopic lenses to photograph the asteroid Psyche’s surface in different wavelengths of light. The color and shape of a planetary body’s spectrum can reveal details about what it’s made of. The Moon and the giant asteroid Vesta, for example, have similar kinds of “bumps and wiggles” in their spectra that scientists could potentially also detect at Psyche. Members of the mission’s science team are interested in Psyche because it will help them better understand the formation of rocky planets with metallic cores, including Earth.
      When choosing targets for the imager testing and calibration, scientists look for bodies that shine with reflected sunlight, just as the asteroid Psyche does. They also look at objects that have a spectrum they’re familiar with, so they can compare previous telescopic or spacecraft data from those objects with what Psyche’s instruments observe. Earlier this year, Psyche turned its lenses toward Jupiter and Mars for calibration — each has a spectrum more reddish than the bluer tones of Earth. That checkout also proved a success.
      The Psyche spacecraft is taking a spiral path around the solar system in order to get a boost from a Mars gravity assist in 2026. It will arrive at the asteroid Psyche in 2029. NASA/JPL-Caltech To determine whether the imager’s performance is changing, scientists also compare data from the different tests. That way, when the spacecraft slips into orbit around Psyche, scientists can be sure that the instrument behaves as expected.
      “After this, we may look at Saturn or Vesta to help us continue to test the imagers,” said Jim Bell, the Psyche imager instrument lead at Arizona State University in Tempe. “We’re sort of collecting solar system ‘trading cards’ from these different bodies and running them through our calibration pipeline to make sure we’re getting the right answers.”
      Strong and Sturdy
      The imager wasn’t the only instrument that got a successful checkout in late July: The mission team also put the spacecraft’s magnetometer and the gamma-ray and neutron spectrometer through a gamut of tests — something they do every six months.
      “We are up and running, and everything is working well,” said Bob Mase, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “We’re on target to fly by Mars in May 2026, and we are accomplishing all of our planned activities for cruise.”
      That flyby is the spacecraft’s next big milestone, when it will use the Red Planet’s gravity as a slingshot to help the spacecraft get to the asteroid Psyche. That will mark Psyche’s first of two planned loops around the solar system and 1 billion miles (1.6 billion kilometers) since launching from NASA’s Kennedy Space Center in October 2023.
      More About Psyche
      The Psyche mission is led by ASU. Lindy Elkins-Tanton of the University of California, Berkeley is the principal investigator.A division of Caltech in Pasadena, JPL is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis. ASU leads the operations of the imager instrument, working in collaboration with Malin Space Science Systems in San Diego on the design, fabrication, and testing of the cameras.
      Psyche is the 14th mission selected as part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. NASA’s Launch Services Program, based at Kennedy, managed the launch service.

      5 Min Read NASA, Army National Guard Partner on Flight Training for Moon Landing
      By Corinne Beckinger
      When Artemis astronauts land on the Moon’s South Pole in a commercial human landing system, they will encounter a landscape pockmarked with deep craters, sloped connecting ridges, and harsh lighting conditions. The Moon’s lack of contrast, combined with its rolling terrain, will also pose a challenge, making it difficult for astronauts to overcome visual illusions on the lunar surface.
      NASA astronaut Bob Hines (left) and Colorado Army National Guard HAATS instructor Ethan Jacobs practice landing procedures in the Rocky Mountains of Colorado in April 2025. Depending on the season, the snowy or dusty conditions can cause visual obstruction. Lunar dust can cause similar visual impairment during future crewed missions. In the mountains of northern Colorado, NASA and the U.S. Army National Guard are using military helicopters to develop a foundational lunar landersimulated flight training course to help astronauts practice flight and landing procedures for the Moon. 
      For decades, military helicopter pilots have trained at the HAATS (High-Altitude Army National Guard Aviation Training Site) in Gypsum, Colorado. In 2021, NASA and the Colorado Army National Guard began working together to develop a course specifically for the next generation of lunar explorers.
      That NASA-specific course is scheduled to be finalized in August 2025, marking an important milestone for Artemis crewed landings training efforts.
      “NASA is using a three-pronged approach with motion-based simulation, in-flight lunar landing analog training, and in-flight lunar simulation to build out its foundational training for Artemis Moon landings,” said NASA astronaut Doug Wheelock, who helped coordinate the training program. “Helicopters at or above 10,000 feet are not really efficient in the thin air, forcing us into operating with very thin power margins similar to the Apollo astronauts having to manage energy and momentum to land safely. The operations along with the terrain at the HAATS course in Colorado’s Rocky Mountains provide a valuable, real-world opportunity for Artemis astronauts to practice flying and landing in conditions similar to maneuvering a lander in the lunar environment.”
      NASA astronaut Raja Chari participates in the HAATS course in April 2025. Since 2021, 22 NASA astronauts and one ESA (European Space Agency) astronaut have participated and evaluated the course based on functionality and Artemis mission needs. NASA/Laura Kiker NASA astronaut Raja Chari participates in the HAATS course in April 2025. Since 2021, 22 NASA astronauts and one ESA (European Space Agency) astronaut have participated and evaluated the course based on functionality and Artemis mission needs. NASA/Corinne Beckinger NASA’s human landing systems that will safely transport astronauts to and from the Moon’s surface will be provided by SpaceX and Blue Origin.
      NASA’s Artemis III mission will build on earlier test flights and add new capabilities, including SpaceX’s Starship Human Landing System and advanced spacesuits, to send the first astronauts to explore the lunar South Pole and prepare humanity to go to Mars.
      While each industry provider is responsible for training Artemis astronauts on its specific lander, NASA is establishing foundational training to help prepare astronauts for crewed flights.
      Flight training opportunities like this are vital to mission success and crew safety.”
      Doug Wheelock
      NASA Astronaut
      “Over the last few years, NASA and the Army National Guard have worked closely to evaluate training procedures and landing zone areas, incorporating accounts from Apollo astronauts,” Wheelock said. “During training flights at HAATS, astronauts can experience the visual illusions, cross-cockpit communication, and degraded visibility they may experience navigating to their landing zone near the lunar south pole. Flight training opportunities like this are vital to mission success and crew safety.”
      Paired with trained instructors from the Army National Guard, astronauts fly to mountaintops and valleys in a range of aircraft, including LUH-72 Lakotas, CH-47 Chinooks, and UH-60 Black Hawks.
      While one astronaut pilots the aircraft, an astronaut in the back charts the landing area, marking key landmarks, identifying potential hazards, and helping to track the flight path. Throughout the week-long course, the landing zones and situations become more challenging, allowing astronauts to experience team dynamics and practice communication skills they will need to land on the Moon.
      “Our full-time Colorado Army National Guard pilots have thousands of flight hours navigating the Rocky Mountains at altitudes ranging from 6,500 to 14,200 feet, and we are reaching new heights by providing realistic and relevant training with NASA for Artemis,” said first sergeant Joshua Smith of the HAATS program. “Our Colorado Army National Guard pilots may not fly around the Moon, but we wear our motto, de monitbus ad astra — from the mountains to the stars — with pride.”
      Fast Facts
      On the Moon’s South Pole, the Sun is never more than 1.5 degrees above or below the horizon. With the Sun at such a low angle and with only a thin exosphere, shadows are stark, and astronauts may find it difficult to determine distances and heights.

      The Moon’s atmosphere is extremely thin, with few particles, and is called an exosphere. The Moon’s exosphere is thin enough to glow in sunlight, which has been observed by spacecraft and some of the Apollo astronauts. The Moon’s surface is challenging to land on. There are inactive volcanoes, bounders, large basins, craters, and cracks in the Moon’s crust, caused by the Earth’s gravity tugging on the Moon. Moon dust can also obscure the view from the windows of a commercial human landing system, and affect sensors that relay important information, such as altitude and velocity, to astronauts. Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.
