Since its arrival in the solar system in 2017, interstellar object 'Oumuamua has puzzled scientists. Two American astronomers now think they have solved one of the space rock's biggest mysteries.

The 3D-printed Terran 1 rocket made by California-based company Relativity Space is waiting on a launchpad in Cape Canaveral ahead of its next debut launch attempt.

A 'hole' in the sun's upper atmosphere may soon generate another geomagnetic storm here on Earth, creating auroras in places farther from the poles than usual.

The Air Force general overseeing North American airspace refused to rule out extraterrestrial forces at play after unidentified objects were shot down in February.

JWST just peered directly into the atmosphere of the giant exoplanet VHS 1256 b and found a roiling world with turbulent clouds made of silicates, similar to sand here on Earth.

Thanks to stunning footage captured by two Mars orbiters, space fans can take a flight through Jezero Crater, the ancient lakebed that's the home of NASA's Perseverance rover.

Global sea levels rose more slowly in 2022 than models predicted. But there's no reason to celebrate, according to NASA.

An image of a crater rim near the moon's south pole shows how NASA's ShadowCam instrument is shining new light on the darker regions of our celestial neighbor.

The UN's final IPCC report warns that drastic action must be taken immediately, but staving off disaster is within humanity's grasp.

But the new result is controversial.

Careful scrutiny of the debris from the impact of NASA's DART mission into Dimorphos has not found any evidence for water ice on the asteroid, nor the residue of thruster fuel from the spacecraft.

An organic compound that's part of the RNA molecules that transmit genetic information in cells has been discovered in samples from the asteroid Ryugu, suggesting the stuff of life came from space.

Astronomers have discovered several fascinating features in galaxy cluster Abell 1213 such as a central galaxy with a 1.66 million light-year-long radio "tail" and remains of galactic mergers.

NASA's Solar Dynamics Observatory captured what might be 'the tallest tornado' in the solar system swirling across the north pole of the sun.

The Uranus moons Ariel and Miranda may have active oceans blasting plumes of particles into space, a new look at data collected by NASA's Voyager 2 spacecraft suggests.

A new method could allow astronomers to assess exoplanets' likely subsurface water stores, aiding the search for worlds capable of supporting life as we know it.

Astronomers have completed the first map of water distribution on the moon, including that more water is found in shaded lunar regions than in sunlit ones.

Even quiet red dwarfs are prone to extreme outbursts that put our sun to shame, with significant implications on the search for alien life.
