In space, far from the strong tug of Earth’s gravity, astronauts experience a number of changes that could affect their health. Understanding these effects of weightlessness, as well as how to treat them, will be vital to a successful future for humans in space.
The spiral arms of the galaxy NGC 3318 are lazily draped across this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies in the constellation Vela and is roughly 115 light-years away from Earth.
Tom Jacobs of Bellevue, Washington, loves treasure hunts. Since 2010, the former U.S. naval officer has participated in online volunteer projects that allow anyone who is interested — “citizen scientists” — to look through NASA telescope data for signs of exoplanets, planets beyond our solar system...
Scientists and engineers operating NASA’s James Webb Space Telescope will answer questions about the mission’s latest milestones in a NASA Science Live broadcast at 3 p.m. EST Monday, Jan. 24, followed by a media teleconference at 4 p.m.
Black holes are often described as the monsters of the universe – tearing apart stars, consuming anything that comes too close, and holding light captive. Detailed evidence from NASA's Hubble Space Telescope, however, shows a black hole in a new light: fostering, rather than suppressing, star... Read More
Within the first year of operations, NASA’s James Webb Space Telescope will help researchers complete a more detailed sketch of the stellar life cycle with high-resolution infrared-light images of 19 galaxies.
NASA has developed a new type of instrument that can provide key information to predict and understand solar flares.
After analyzing powdered rock samples collected from the surface of Mars by NASA’s Curiosity rover, scientists today announced that several of the samples are rich in a type of carbon that on Earth is associated with biological processes.
Are there rainbows on Mars? Sadly, no. But there are a whole lot of other conditions on Mars that we have right here on Earth! NASA scientist Mark Lemmon explains why the Red Planet is a rainbowless world. Get more Martian science: www.nasa.gov/mars

This data is the live status of the James Webb space telescope provided by NASA. In this NASA Live Tracker, you will get real-time info about the distance covered by JWST, its speed, and the distance that is remaining to reach L2 orbit.
The lazily winding spiral arms of the spectacular galaxy NGC 976 fill the frame of this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies around 150 million light-years from the Milky Way in the constellation Aries.
Citizen Scientists Spot Jupiter-like Planet in NASA TESS Data
We answers six questions to help you understand the GISS global surface temperature analysis, what it shows about 2021 and how NASA makes sense of the data.
Earth’s global average surface temperature in 2021 tied with 2018 as the sixth warmest on record, according to independent analyses done by NASA and the National Oceanic and Atmospheric Administration (NOAA).
