The two interacting galaxies making up the pair known as Arp-Madore 608-333 seem to float side by side in this image from the NASA/ESA Hubble Space Telescope. Though they appear serene and unperturbed, the two are subtly warping one another through a mutual gravitational interaction that is disrupting and distorting both galaxies. Hubble’s Advanced Camera fo...
The Sun released an X1 solar flare, a powerful burst of energy, captured by our Solar Dynamics Observatory (SDO) on Oct. 2, 2022. X-class are the most intense flares, while the number provides more information about its strength. For instance, an X1 flare is half as strong as an X2. While solar flares can affect radio communications, power grids, and navigat...
In this 20-second exposure from Oct. 5, 2022, a SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched on NASA’s SpaceX Crew-5 mission from our Kennedy Space Center in Florida to the International Space Station (ISS). This is the fifth crew rotation mission of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the ISS as...
Astronaut Serena Auñón-Chancellor installs samples for the Microgravity Investigation of Cement Solidification (MICS) experiment aboard the International Space Station (ISS) in this image from Nov. 27, 2018. MICS explored how cement solidified in microgravity, important research for constructing safe space habitats on the Moon or Mars and for improving cemen...
Astronaut Nicole Mann sits inside a T-38 trainer jet at Ellington Field in Houston, Texas, in this image from Nov. 15, 2018. She served as the T-38 safety and training officer; T-38s are used for pilot proficiency and training for astronauts. Selected as an astronaut candidate in June 2013, Mann will be the first Indigenous woman from NASA in space. In her f...
This is the last complete image of the asteroid Dimorphos, as seen by our Double Asteroid Redirection Test (DART) two seconds before impact. The Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO) imager aboard captured a 100-foot-wide patch of the asteroid. The DART spacecraft streamed these images from its DRACO camera back to Earth i...
On Sept. 21, 2022, the James Webb Space Telescope delivered the clearest view of Neptune’s rings in more than 30 years. Webb’s Near-Infrared Camera (NIRCam) captured several bright, narrow rings as well as the planet’s fainter dust bands. Voyager 2 was the last to detect some of these rings during its flyby in 1989, but this is the first time we have an infr...
Astronaut Ellen Ochoa, STS-110 flight engineer, wears a launch and entry suit as part of water survival training in the Neutral Buoyancy Laboratory at the Sonny Carter Training Facility near NASA’s Johnson Space Center in Houston, Texas in 2001. STS-110 was the 13th shuttle mission to visit the International Space Station (ISS). The mission included 4 spacew...
In this image from Sept. 26, 2022, the Double Asteroid Redirection Test (DART) team, Dr. Thomas Zurbuchen, and guests at Johns Hopkins University Applied Physics Laboratory cheer as they receive confirmation of DART’s collision with the asteroid Dimorphos—the world’s first planetary defense technology demonstration. During the spacecraft’s final moments befo...
Technicians prepare to move NASA’s Double Asteroid Redirection Test (DART) spacecraft from a shipping container onto a work stand inside the Astrotech Space Operations Facility at Vandenberg Space Force Base in California in this image from Oct. 4, 2021. DART was launched on Nov. 23, 2021, aboard a SpaceX Falcon 9 rocket from Vandenberg. The spacecraft will ...
