In the background is the 209-foot-tall U.S. flag painted on the side of the 52-story Vehicle Assembly Building, which serves as the central hub of NASA’s p...
NASA’s Oceans Melting Greenland, or OMG, airborne mission found that most of Greenland’s glaciers that empty into the ocean are at greater risk of rapid ice loss than previously understood. OMG’s six-year field campaign studied the ocean’s role in glacial ice loss by gathering precise measurements of ocean depth, temperature, and sali...
In this image from 2014, brightly glowing plumes of the Large Magellanic Cloud (LMC) appear almost like an ocean current with turquoise-tinted currents and nebulous strands reaching out into the surroundings. This image shows part of the Tarantula Nebula’s outskirts located within the LMC, a small nearby galaxy that orbits the Milky Way and appears as ...

The people that ...
CAPSTONE, the pathfinder for NASA’s lunar outpost, will test an orbit around the Moon that has never been flown before. In this image from April 2022, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, was undergoing final construction – and with solar panel installation and vibration testing now complete...
After completing two additional mirror alignment steps in March 2022, the team confirmed the James Webb Space Telescope’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve. This “selfie” was created using a specialized pupil imaging lens inside of Webb’s Near Infrared Camera, or NIRCam, instrument...
The Hubble Space Telescope captured this glittering scene using its Wide Field Camera 3 and Advanced Camera for Surveys. Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars. As this image demonstrates, the hearts of globular clusters are densely packed with stars. Terzan 9 is dotted with so many glittering stars that ...
