Micrometeoroid

Scientists have hypothesized since the 1960s that the Sun is a source of ingredients that form water on the Moon. When a stream of charged particles known as

NASA 's astronauts aboard the International Space Station have been told to prepare for an urgent evacuation amid growing safety concerns.

Minuscule meteoroids slamming into the lunar surface could be kicking up most of the atoms that make up the lunar exosphere.

Researchers used observations from the Webb Telescope to identify carbon dioxide and hydrogen peroxide on the surface of Charon, Pluto's largest moon.

Could its unorthodox approach make it more dangerous for astronauts?

Wispy whorls on the moon's surface are as lovely as they are strange. Scientists are starting to unravel their origins

While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—is likely a product of some kind of space weathering. But exactly what those processes might be has been difficult to pin down with any certainty.

An Italian-led team of scientists say they have confirmed evidence of a sizable cave on the moon not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago.

The latest image from the James Webb telescope shows a pair of intertwined galaxies, known as Arp 142, and nicknamed the Penguin and the Egg.

The Indian Space Research Organisation's historic Chandrayaan-3 moon lander managed to keep moon dust off its cameras thanks to a special engine setup.

JWST is now celebrating its second anniversary in space.

The coolant leak in the experiment radiator follows similar leaks in a Soyuz crew ferry ship and a Progress cargo craft.

After spending more than a year in space, Frank Rubio now has to get used to that pesky thing Earthlings call gravity.

NASA and Russian officials are investigating a new leak aboard the International Space Station. The Russian Nauka science module sprung a leak in a 13-year...

For the third time in a year, coolant is leaking from a Russian module aboard the International Space Station

A recently published study suggests that Saturn's rings formed after two icy moons collided a few hundred million years ago. Other evidence indicates that the orbiting dust...

NASA's Frank Rubio broke the record for the longest stay in space by a US astronaut. Now, he's finally back home.

Frank Rubio and two cosmonaut crewmates return to Earth next Wednesday to wrap up a U.S. record 371-day stay in orbit.

"I'm really excited to see how my body does when I return."

Frank Rubio moved past NASA astronaut Mark Vande Hei's 355-day record on the way to spending more than a full year in space.
