The DART spacecraft's tiny companion is ready to photograph a brand-new impact site Monday night (Sept. 26).
For NASA's DART spacecraft, the drama happens in space, but mission success relies on telescopes back on Earth.
When NASA's DART mission slams itself into an asteroid called Dimorphos, three different science spacecraft will be trying to watch the action.
Scientists expected that the lander would run out of power by the end of the summer, but InSight is still eking out science data and may for several months to come — potentially even into January.
Satellites are watching as Hurricane Fiona, currently a Category 1 storm, pummels Caribbean islands.
On Sept. 26, DART will slam headfirst into a small asteroid, the rare case when a spacecraft's destruction is the desired outcome.
Astronomers have written the Milky Way's story many times over; scientists have traced violent collisions in its past and future and peered into the supermassive black hole lurking at its heart.
Lindy Elkins-Tanton offers a very human view of her experiences in science and life alike in her new memoir, "A Portrait of the Scientist as a Young Woman."
Even NASA's newest observatory can't manage to see supermassive black holes directly, but that doesn't mean astronomers can't use its data to better understand the mysterious behemoths.
A SpaceX Falcon 9 rocket took the scenic route as it lofted 46 Starlink satellites to orbit on Friday (July 22).
As highly anticipated as the first science-quality images from the James Webb Space Telescope will be, they aren't the first photos from the massive space observatory.
It was an emotional day for scientists as they shared with the world the first science-quality images from NASA's next-generation observatory.
Next time the Event Horizon Telescope turns to study the monster black hole at the center of the Milky Way, it will have help from the James Webb Space Telescope.
A planned reboost maneuver of the International Space Station ended after just 5 seconds for reasons currently unknown.
NASA has arranged for a team of scientists to spend nine months evaluating unidentified aerial phenomena, or UAPs.
NASA's next-generation space observatory has sustained its first noticeable micrometeoroid impact less than six months after launch, but the agency isn't too concerned.
