The moon has more hidden pockets of water ice than previously thought, NASA's SOFIA flying observatory reveals.
This supermassive black hole's spin has been measured for the first time, and it's surprisingly low.
A pair of astronomers is advocating a daring new research program: to turn our widening search for life beyond Earth into a hunt for dark matter.
A NASA spacecraft has really made a mess of things on the asteroid Bennu, and scientists are thrilled.
The search for dark matter is at a crossroads. Now, physicists have a new way to tell what the invisible stuff is made of.
Humans have gotten good at spotting planets orbiting alien stars. But how many of those alien stars are able to look back and see us?
The most hazardous part of the mission is over – and seemingly successful, although we will have to wait for a few more days to hear the scale of the success.
Starman — the dummy riding a Tesla Roadster through space — has made his closest approach ever to Mars since his stunt launch in 2018.
For the first time ever, a NASA probe has performed a sample-snagging operation on an asteroid in deep space.
Physicists suggest harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick? Carefully set everything up so the particles don't get lost forever.
As soon as he saw the data, Paul Chodas knew something was strange about the near-Earth object that had been designated 2020 SO.
An object identified earlier this year as the closest black hole we've ever discovered may have just been demoted.
Back in 2016, researchers claimed Dragonfly 44 was a "failed" Milky Way — a galaxy with a huge dark matter mass but almost no stars. Now, on closer examination, that claim has fallen apart.
Only eight countries have signed the Artemis Accords, a set of guidelines surrounding the Artemis Program for crewed exploration of the moon.
The fluid that cushions the human brain redistributes in the skull during spaceflight, according to a new study.
If the Higgs boson really is decaying into pairs of muons in the Large Hadron Collider, that's a big deal for particle physics.
NASA's OSIRIS-Rex spacecraft will "TAG" asteroid Bennu Tuesday (Oct. 20) and collect a sample for return to Earth.
Researchers have found a way to trap and study elusive particle trios called trions at room temperature.
