For this image, the NASA/ESA Hubble Space Telescope turned its powerful eye toward an emission-line galaxy called NGC 3749. It lies over 135 million light-years away and is moderately luminous.

In the Phoenix constellation, astronomers have confirmed the first example of a galaxy cluster where large numbers of stars are being born at its core.

When the Earth moved directly between the Sun and the Apollo 12 spacecraft on the journey home from the Moon, the crew captured this image of a solar eclipse a 16mm motion picture camera. Aboard the craft were Commander Charles "Pete" Conrad; command module pilot Richard F. Gordon Jr. and lunar module pilot Alan Bean.

This view from NASA's Juno spacecraft captures colorful, intricate patterns in a jet stream region of Jupiter's northern hemisphere known as "Jet N3."

This image of star trails was compiled from time-lapse photography taken by NASA astronaut Christina Koch while onboard the International Space Station.

The Medusa merger, was not always one entity, but two. An early galaxy consumed a smaller gas-rich system, throwing out streams of stars and dust into space. These streams resemble the writhing snakes that Medusa, a monster in ancient Greek mythology, famously had on her head in place of hair, lending the object its intriguing name.

Astronomers have detected X-rays from Uranus for the first time, using NASA’s Chandra X-ray Observatory, as shown in this image from March 2021.

Today is my last Monday living on this orbiting laboratory and I’m soaking up my final views, said astronaut Nick Hague.

Expedition 60 astronaut Christina Koch photographed the Soyuz MS-15 crew ship ascending into space after its launch from Kazakhstan.

In this image, a galaxy called ESO 243-49 is home to an extremely bright object called HLX-1. Circled in this image, HLX-1 is the most likely example of a black hole in the intermediate mass range that scientists have found.

Tethys appears to be stuck to Saturn's A and F rings from this perspective.

Because they lack stellar nurseries and contain mostly old stars, elliptical galaxies — Like Messier 110 — are often considered “dead” when compared to their spiral relatives. But scientists have spotted signs of a population of young, blue stars at Messier 110's center, hinting that this neighbor of our Milky Way may not be so “dead” after all.

This image shows sedimentary rock and sand within Danielson Crater, an impact crater about 42 miles or 67 kilometers in diameter, located in the southwest Arabia Terra region of Mars.

Located in the northern constellation of Ursa Major, which also includes the Big Dipper, nearby galaxy Messier 81 is easily visible through binoculars or a small telescope.

NASA astronaut Christian Koch snapped this image of Hurricane Dorian as the International Space Station during a flyover on Monday, September 2, 2019.

NGC 5307, a planetary nebula that lies about 10,000 light-years from Earth, can be seen in the constellation Centaurus.

Spitzer Space Telescope into orbit around the Sun on Aug. 25, 2003. Since then, the observatory has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light.

West Point graduate, physician and NASA astronaut Andrew Morgan is pictured working outside the International Space Station .

In 1967, Christine Darden was added to the pool of 'human computers' who wrote complex programs and tediously crunched numbers for engineers at NASA's Langley Research Center.

This galactic duo is known as UGC 2369. The galaxies are interacting, meaning that their mutual gravitational attraction is pulling them closer and closer together and distorting their shapes in the process.

The sharply angled perspective in this Hubble image of spiral galaxy NGC 3169 makes it seem as if we, the viewers, are craning our necks to see over a barrier into the galaxy's bright center. In the case of NGC 3169, this barrier is the thick dust embedded within the galaxy's spiral arms.

The Apollo 11 Command Module is hoisted aboard the USS Hornet, the prime recovery vessel for the historic Apollo 11 lunar landing mission.

In July 1964, the first Saturn V S-IVB, or third stage test hardware, was delivered to NASA’s Marshall Space Flight Center

This stunning image of Jupiter's stormy northern hemisphere was captured by NASA's Juno spacecraft as it performed a close pass of the gas giant planet.

The Soyuz MS-11 spacecraft is seen as it lands in a remote area near the town of Zhezkazgan, Kazakhstan with Expedition 59 crew members.

At 5:30 a.m. EDT Thursday, June 20, 2019, a 40-foot tall rocket carrying 28 student experiments (measuring acceleration, humidity, pressure, temperature and radiation counts) launched from Wallops Flight Facility in Virginia.

"Years ago at the South Pole, I looked up to the aurora for inspiration through the 6-month winter night." Aboard the International Space Station, NASA astronaut Christina Koch snapped this image of an aurora.

From the International Space Station, NASA astronaut Christina Koch snapped and posted this image of the planet Venus at sunrise.

This luminous orb is the galaxy NGC 4621, better known as Messier 59. Located in the 2,000-strong Virgo cluster of galaxies within the constellation of Virgo (the Virgin), Messier 59 lies approximately 50 million light-years away from us.
