Earth will become too hot to handle in a billion years. There's a (very) remote chance a passing star could save us by knocking our planet back into the habitable zone.

Unvisited by spacecraft for more than 35 years, Uranus inhabits one of the least explored regions of our solar system.

There will be 20 total payloads being brought to the moon, five of which are NASA's.

"This discovery really drives home the point of just how little we know about the universe. We wouldn’t expect a planet this heavy around such a low-mass star to exist."

For the first time since its discovery, scientists have found stars within the Magellanic Stream, a mighty river of hydrogen gas emanating from two small galaxies in the outskirts of the Milky Way.

The discovery is another step along the road to showing that the stuff of life originally came to Earth from space.

For the first time, NASA-funded researchers can apply for access to lunar samples collected by China's Chang'e-5 mission.

Radio signals in Earth's orbit can create noise in astronomy data. Scientists are planning a workaround that'll be available to researchers for free.

Astronomers have discovered around 300 new gamma-ray-blasting pulsars, including several "spider pulsars" that devour the companion stars like black widows.

Asteroid Dinkinesh, target No. 1 on Lucy's journey, turned out to be not one, but two (technically three) space rocks put together. Scientists finally gave its satellite a name.

The Hubble Space Telescope has entered an automatic safe mode due to gyroscope difficulties, but scientists aren't worried about the observatory's health.

Spectral analysis of the mystery asteroid Phaethon reveals its composition at last.

All solar system planets circle our sun with slightly tilted orbits — and a new study shows even distant planetary systems in quiet neighborhoods have orbital tilts, too.

El Niño is in full swing and will likely remain "strong" this winter, but its effect on weather patterns in the U.S. depends on the behavior of an unusually warm blob in the western Pacific, experts say.

The James Webb Space Telescope has found water and organic carbon molecules in the vicinity of a massive, active young star.

The world's largest iceberg, known as A23a, has broken loose and is moving past the northern tip of the Antarctic Peninsula in new satellite images from the Copernicus Sentinel-1 mission.

Astronomers have spotted an accretion disk feeding matter to a young star and helping it grow in a galaxy outside the Milky Way for the first time.

A newfound, and impressively well-maintained, planetary system full of sub-Neptunes could reveal why our solar system lacks such a world.

This might indicate a "glaciological tipping point" on the Antarctic Peninsula, an important consideration as global warming continues to affect ocean temperatures.
