In what's beginning to look like a case of planetary measles, a third red spot has appeared alongside its cousins – the Great Red Spot and Red Spot Jr. – in the turbulent Jovian atmosphere. This third red spot, which is a fraction of the size of the two other features, lies to the west of the Great Red Spot in the same latitude band of clouds. The visible-light images were taken on May 9 and 10 with Hubble's Wide Field and Planetary Camera 2.

      The International Space Station is seen in this 30 second exposure as it flies over Elkton, VA early in the morning, Saturday, August 1, 2015. NASA/Bill Ingalls Time is when the sighting opportunity will begin in your local time zone. All sightings will occur within a few hours before or after sunrise or sunset. This is the optimum viewing period as the sun reflects off the space station and contrasts against the darker sky. Visible is the maximum time period the space station is visible before crossing back below the horizon. Max Height is measured in degrees (also known as elevation). It represents the height of the space station from the horizon in the night sky. The horizon is at zero degrees, and directly overhead is ninety degrees. If you hold your fist at arm’s length and place your fist resting on the horizon, the top will be about 10 degrees. Appears is the location in the sky where the station will be visible first. This value, like maximum height, also is measured in degrees from the horizon. The letters represent compass directions — N is north, WNW is west by northwest, and so on. Disappears represents where in the night sky the International Space Station will leave your field of view. The International Space Station orbits with an inclination of 51.6 degrees. This means that, as it orbits, the farthest north and south of the Equator it will ever go is 51.6 degrees latitude. If you live north or south of 51.6 degrees, the ISS will never go directly over your head- this includes places like Alaska. Spot The Station may not properly inform you of all visible space station passes in these locations. Spot The Station’s sighting opportunities pages will give you a list of all possible space station sightings for your location.NASA Important: The International Space Station orbits with an inclination of 51.6 degrees.

      The space station looks like an airplane or a very bright star moving across the sky, except it doesn’t have flashing lights or change direction. It will also be moving considerably faster than a typical airplane (airplanes generally fly at about 600 miles (965 km) per hour; the space station flies at 17,500 miles (28,000 km) per hour).

      An astronaut aboard the International Space Station adjusted the camera for night imaging and captured the green veils and curtains of an aurora that spanned thousands of kilometers over Quebec, Canada.NASA Why is the space station up there?
      The space station is Earth’s only microgravity laboratory. This football field-sized platform hosts a plethora of science and technology experiments that are continuously being conducted by crew members, or are automated. Research aboard the orbiting laboratory holds benefits for life back on Earth, as well as for future space exploration. The space station serves as a testbed for technologies and allows us to study the impacts of long-term spaceflight to humans, supporting NASA’s mission to push human presence farther into space. Learn more about the research happening on the space station, and opportunities to conduct your science there.
      The sighting opportunity schedule indicates that the space station passed over my house last night; I’m signed up for alerts but didn’t get one, why not?
      You will only receive an alert if the space station will reach a max height of at least 40° on flyover. Flyovers reaching at least 40° provide the best chance for a sighting opportunity because they are visible above most landscapes and buildings. Check the “Max Height” column of your sighting opportunity schedule for the flyovers that are 40° or more.
      The flyover schedule indicates the space station is both appearing and disappearing from the same direction, how is that possible? E.g. – Time: Mon Jul 15 11:57 PM, Visible: 2 min, Max Height: 51°, Appears: 51° above ENE, Disappears: 11° above ENE
      The Spot the Station software rounds off directions to the nearest cardinal and intracardinal directions. This can result in it seeming as though the ISS will be appearing and disappearing in the same direction even though it is traveling across the sky. This typically happens on flyovers with a short window of visibility because the ISS is quickly moving into (or out of) the Earth’s dark shadow where, from our location on the ground, we can’t observe its full pass across the sky.
      How often can I expect to see the space station?
      The space station is visible because it reflects the light of the Sun – the same reason we can see the Moon. However, unlike the Moon, the space station isn’t bright enough to see during the day. It can only be seen when it is dawn or dusk at your location. As such, it can range from one sighting opportunity a month to several a week, since it has to be both dark where you are, and the space station has to happen to be going overhead.
      Why aren’t there any sighting opportunities for my location?
      It needs to be dark where you are and the space station needs to be overhead in order for you to see it. Since the space station’s orbit takes it all around the globe, it can be passing over you at times when it will not be visible- either in the middle of the day or the middle of the night. The space station must be 40 degrees or more above the horizon for it to be visible. Spot The Station will only send out notifications when you will have an opportunity to see the space station, not every time it will be overhead.
      Do I need a telescope to see the space station?
      No, you can see the space station with your bare eyes, no equipment required.
      Can you explain how to identify the space station in the sky? Did I see the space station last night?
      The space station looks like an airplane or a very bright star moving across the sky, except it doesn’t have flashing lights or change direction. It will also be moving considerably faster than a typical airplane (airplanes generally fly at about 600 miles (965 km) per hour; the space station flies at 17,500 miles (28,000 km) per hour).

      The ISS circles the Earth every 90 minutes. It travels at about 17,500 miles (28,000 km) per hour, which gives the crew 16 sunrises and sunsets every day. In the more than 15 years that people have been living onboard, the Station has circumnavigated the Earth tens of thousands of times. You can see more facts about the ISS on the Space Station: Facts and Figures webpage .
      Does the station appear and then disappear because of the light of the Moon?
      The space station is visible because it is reflecting light from the Sun. This is the same reason that the Moon appears to shine. Even when the Moon hasn’t risen, you’ll still be able to see the space station.

      December’s Night Sky Notes: Spot the King of Planets
      by Kat Troche of the Astronomical Society of the Pacific
      Jupiter is our solar system’s undisputed king of the planets! Jupiter is bright and easy to spot from our vantage point on Earth, helped by its massive size and banded, reflective cloud tops. Jupiter even possesses moons the size of planets: Ganymede, its largest, is bigger than the planet Mercury. What’s more, you can easily observe Jupiter and its moons with a modest instrument, just like Galileo did over 400 years ago.
      This image taken on Feb. 7 by NASA’s Juno spacecraft, reveals swirling cloud formations in the northern area of Jupiter’s north temperate belt. Citizen scientist Kevin M. Gill processed the image using data from the JunoCam imager. NASA, JPL-Caltech, SwRI, MSSS | Image processing by Kevin M. Gill, © CC BY Jupiter’s position as our solar system’s largest planet is truly earned; you could fit 11 Earths along Jupiter’s diameter, and in case you were looking to fill up Jupiter with some Earth-size marbles, you would need over 1300 Earths to fill it up – and that would still not be quite enough! However, despite its formidable size, Jupiter’s true rule over the outer solar system comes from its enormous mass. If you took all of the planets in our solar system and put them together, they would still only be half as massive as Jupiter all by itself. Jupiter’s mighty mass has shaped the orbits of countless comets and asteroids. Its gravity can fling these tiny objects towards our inner solar system and also draw them into itself, as famously observed in 1994 when Comet Shoemaker-Levy 9, drawn towards Jupiter in previous orbits, smashed into the gas giant’s atmosphere. Its multiple fragments slammed into Jupiter’s cloud tops with such violence that the fireballs and dark impact spots were not only seen by NASA’s orbiting Galileo probe but also by observers back on Earth! 
      Look for Jupiter near the Eye of the Bull, Aldebaran, in the Taurus constellation on the evening of December 15, 2024. Binoculars may help you spot Jupiter’s moons as small bright star-like objects on either side of the planet. A small telescope will show them easily, along with Jupiter’s famed cloud bands. How many can you count? Credit: Stellarium Web Jupiter is easy to observe at night with our unaided eyes, as well-documented by the ancient astronomers who carefully recorded its slow movements from night to night. It can be one of the brightest objects in our nighttime skies, bested only by the Moon, Venus, and occasionally Mars, when the red planet is at opposition. That’s impressive for a planet that, at its closest to Earth, is still over 365 million miles (587 million km) away. It’s even more impressive that the giant world remains very bright to Earthbound observers at its furthest distance: 600 million miles (968 million km)! While the King of Planets has a coterie of 95 known moons, only the four large moons that Galileo originally observed in 1610 – Io, Europa, Ganymede, and Calisto – can be easily observed by Earth-based observers with very modest equipment. These are called, appropriately enough, the Galilean moons. Most telescopes will show the moons as faint star-like objects neatly lined up close to bright Jupiter. Most binoculars will show at least one or two moons orbiting the planet. Small telescopes will show all four of the Galilean moons if they are all visible, but sometimes they can pass behind or in front of Jupiter or even each other. Telescopes will also show details like Jupiter’s cloud bands and, if powerful enough, large storms like its famous Great Red Spot, and the shadows of the Galilean moons passing between the Sun and Jupiter. Sketching the positions of Jupiter’s moons during the course of an evening – and night to night – can be a rewarding project!

      Now in its eighth year, NASA’s Juno mission is one of just nine spacecraft to have visited this impressive world. Juno entered Jupiter’s orbit in 2016 to begin its initial mission to study this giant world’s mysterious interior. The years have proven Juno’s mission a success, with data from the probe revolutionizing our understanding of this gassy world’s guts. Juno’s mission has since been extended to include the study of its large moons, and since 2021 the plucky probe, increasingly battered by Jupiter’s powerful radiation belts, has made close flybys of the icy moons Ganymede and Europa, along with volcanic Io.
