NASA astronaut Jessica Watkins floats in the International Space Station’s cupola, a direct nadir viewing window from which Earth and celestial objects are visible. Watkins reported for duty in August 2017 and completed two years of training as an astronaut candidate. Her astronaut candidate training included scientific and technical briefings, intensive ins...
The SpaceX Crew Dragon Endurance spacecraft is seen shortly after it landed with NASA astronauts Raja Chari, Kayla Barron, Tom Marshburn, and European Space Agency astronaut Matthias Maurer aboard. The craft splashed down in the Gulf of Mexico, off the coast of Tampa, Florida, Friday, May 6, 2022. Maurer, Marshburn, Chari, and Barron are returning after 177 ...
The SpaceX Dragon Endurance spacecraft is seen just after undocking from the forward port of the International Space Station’s Harmony module at 1:20 a.m. EDT, Thursday, May 5, 2022. Endurance is bringing Crew-3 back to Earth, including NASA astronauts Kayla Barron, Raja Chari, and Tom Marshburn, and ESA (European Space Agency) astronaut Matthias Maurer, aft...
Black holes are hard to find. They have such strong gravity that light can’t escape them, so scientists must rely on clues from their surroundings to find them. When a star weighing more than 20 times the Sun runs out of fuel, it collapses into a black hole. Scientists estimate that there are tens of millions of these black holes dotted around the Milky Way,...

Researchers at Arizona State University in Tempe are evaluating a small, lightweight, efficient 3D imaging sensor designed for weather forecasting on consecutive balloon flights made possible by NASA’s Flight Opportunities program. Called CubeSounder, the innovation could benefit future balloon flights and CubeSats by enabling state-of-the-art atmospheric so...
A SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched on NASA’s SpaceX Crew-4 mission to the International Space Station with NASA astronauts Kjell Lindgren, Robert Hines, Jessica Watkins, and European Space Agency astronaut Samantha Cristoforetti onboard, Wednesday, April 27, 2022, at NASA’s Kennedy Space Center in Florida...
This Hubble Space Telescope image features two merging galaxies in the VV-689 system, nicknamed the Angel Wing. Unlike chance alignments of galaxies, which only appear to overlap when viewed from our vantage point on Earth, the two galaxies in VV-689 are in the midst of a collision. The galactic interaction has left the VV-689 system almost completely symmet...
