Jupiter and Venus shine brightly in the mornings as they appear to graze each other in the sky on the 11th and 12th. The Perseids are washed out by the Moon.
Skywatching Highlights
All Month – Planet Visibility:
Mercury: Pops up above the horizon during the second half of August. Appears very low, below 10 degrees altitude. Venus: Shines very brightly in the east each morning before sunrise, about 20 to 30 degrees above the horizon. Mars: Can be observed low in the west during the hour after sunset, appearing about as bright as the brightest stars in the Big Dipper. Jupiter: Appears in the east each morning, together with Venus, but much less bright. Saturn: Observable late night to dawn. Rises around 10:30 p.m. early in the month, and around 8:30 p.m. by the end of the month. Find it high in the south as sunrise approaches. Skywatching Highlights:
August 11 & 12 – Venus-Jupiter Conjunction – The two brightest planets have a close meetup over several days, appearing closest over two days on the 11th and 12th, at just a degree apart.
August 19 & 20 – Moon with Jupiter & Venus – A slim lunar crescent joins Jupiter and Venus — still relatively close in the sky after their conjunction. They appear in the east in the several hours preceding sunrise.
August 12th-13th – Perseids Peak – The celebrated annual meteor shower will be hampered by an 84%-full Moon on the peak night. A few bright meteors may still be seen in the pre-dawn hours, but viewing conditions are not ideal this year.
All month – The Dumbbell Nebula (M27) – One of the easiest planetary nebulas to observe, M27 appears within the Summer Triangle star pattern, high overhead in the first half of the night.
Transcript
What’s Up for August? Jupiter and Venus have a morning meetup, we check out this year’s Perseid meteor shower, and peek into the future of our own Sun.
Mars is the lone planet in the early evening sky this month, visible low in the west for about an hour after the sky starts to darken. It’s now only about 60% as bright as it appeared back in May.
Saturn is rising by about 10 pm, and you’ll see it showing up a bit earlier each evening as the month goes on. You’ll find it in the east after dark with the constellations Cassiopeia and Andromeda. The Ringed Planet makes its way over to the western part of the sky by dawn, where early risers will find it on August mornings.
The real highlight of August is the close approach of Jupiter and Venus. They shine brightly in the east before sunrise throughout the month. The pair begin the month farther apart, but quickly approach each other in the sky. They appear at their closest on the 11th and 12th — only about a degree apart. Their rendezvous happens against a backdrop of bright stars including Orion, Taurus, Gemini, and Sirius. A slim crescent Moon joins the pair of planets after they separate again, on the mornings of the 19th and 20th.
Sky chart showing the eastern sky before sunrise on August 11th, with Venus and Jupiter only a degree apart. NASA/JPL-Caltech One of the best annual meteor showers, the Perseids, peaks overnight on August 12th and into the 13th. Unfortunately, this year the Moon is nearly full on the peak night, and its glare will wash out all but the brightest meteors. While that’s not so great for Perseid watchers, the good news is that another favorite annual meteor shower, the Geminids, is poised for Moon-free viewing in December.
August is a great time to see one of the easiest-to-observe nebulas in the sky.
The Dumbbell Nebula, also known as M27, is high overhead on August nights. It’s a type of nebula called a “planetary nebula.”
A nebula is a giant cloud of gas and dust in space, and planetary nebulas are produced by stars like our Sun when they become old and nuclear fusion ceases inside them. They blow off their outer layers, leaving behind a small, hot remnant called a white dwarf. The white dwarf produces lots of bright ultraviolet light that illuminates the nebula from the inside, as the expanding shell of gas absorbs the UV light and re-radiates it as visible light.
The Dumbbell Nebula, nicknamed for its dumbbell-like shape, appears as a small, faint patch of light about a quarter of the width of the full moon in binoculars or a small telescope. It lies within the Summer Triangle, a pattern of stars that’s easy to find overhead in the August sky. You’ll find the nebula about a third of the way between its bright stars Altair and Deneb.

NASA/JPL-Caltech Here’s hoping you get a chance to observe this glimpse into the future that awaits our Sun about 5 billion years from now. It’s part of a cycle that seeds the galaxy with the ingredients for new generations of stars and planets — perhaps even some not too different from our own.
Here are the phases of the Moon for August.

A SpaceX Falcon 9 rocket carrying the company’s Dragon spacecraft is launched on NASA’s SpaceX Crew-11 mission to the International Space Station with NASA astronauts Zena Cardman, Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov onboard, Friday, Aug. 1, 2025, from NASA’s Kennedy Space Center in Florida. NASA’s SpaceX Crew-11 mission is the eleventh crew rotation mission of the SpaceX Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. Cardman, Fincke, Yui, Platonov launched at 11:43 a.m. EDT from Launch Complex 39A at the NASA’s Kennedy Space Center to begin a six month mission aboard the orbital outpost. Credit: NASA/Aubrey Gemignani Four crew members of NASA’s SpaceX Crew-11 mission launched at 11:43 a.m. EDT Friday from Launch Complex 39A at the agency’s Kennedy Space Center in Florida for a science expedition aboard the International Space Station.
A SpaceX Falcon 9 rocket propelled the Dragon spacecraft into orbit carrying NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov. The spacecraft will dock autonomously to the space-facing port of the station’s Harmony module at approximately 3 a.m. on Saturday, Aug. 2.
“Thanks to the bold leadership of President Donald J. Trump, NASA is back! The agency’s SpaceX Crew-11 mission to the space station is the first step toward our permanent presence on the Moon. NASA, in conjunction with great American companies, continues the mission with Artemis in 2026. This Moon mission will ensure America wins the space race – critical to national security – and leads in the emerging, exciting and highly profitable private sector commercial space business,” said acting NASA Administrator Sean Duffy. “The Commercial Crew Program and Artemis missions prove what American ingenuity, and cutting-edge American manufacturing can achieve. We’re going to the Moon…to stay! After that, we go to Mars! Welcome to the Golden Age of exploration!”
During Dragon’s flight, SpaceX will monitor a series of automatic spacecraft maneuvers from its mission control center in Hawthorne, California. NASA will monitor space station operations throughout the flight from the Mission Control Center at the agency’s Johnson Space Center in Houston.
NASA’s live coverage resumes at 1 a.m., Aug. 2, on NASA+ with rendezvous, docking, and hatch opening. After docking, the crew will change out of their spacesuits and prepare cargo for offload before opening the hatch between Dragon and the space station’s Harmony module around 4:45 a.m. Once the new crew is aboard the orbital outpost, NASA will provide coverage of the welcome ceremony beginning at approximately 5:45 a.m.

The number of crew aboard the space station will increase to 11 for a short time as Crew-11 joins NASA astronauts Anne McClain, Nichole Ayers, and Jonny Kim, JAXA astronaut Takuya Onishi, and Roscosmos cosmonauts Kirill Peskov, Sergey Ryzhikov, and Alexey Zubritsky.
NASA’s SpaceX Crew-10 will depart the space station after the arrival of Crew-11 and a handover period. Ahead of Crew-10’s return, mission teams will review weather conditions at the splashdown sites off the coast of California prior to departure from station.
During their mission, Crew-11 will conduct scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Participating crew members will simulate lunar landings, test strategies to safeguard vision, and advance other human spaceflight studies led by NASA’s Human Research Program. The crew also will study plant cell division and microgravity’s effects on bacteria-killing viruses, as well as perform experiments to produce a higher volume of human stem cells and generate on-demand nutrients.
The mission is part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.
