Astronomers have captured a new image of the asteroid 2024 YR4, which now has a 1 in 48 chance of hitting Earth in 2032.

Researchers have discovered that black holes engage in a cosmic dance and a star-lit meal to vibe with each other in a cosmic love story fit for Valentine's Day.

Astronomers have discovered what seems to be a star racing through the Milky Way at 1.2 million mph, dragging a Neptune-sized planet along for the ride.

Captain America: Brave New World is about to hit cinemas, bringing with it the gamma-ray-powered Red Hulk. Here's what you need to know about that high-energy radiation.

"History shows us that whenever you do open a new 'energy window,' you never really know what you're going to find. It's completely unexplored."

Astronomers have been able to image gas as it travels down a 3 million light-year-long cosmic highway between two growing galaxies ensnared in the cosmic web.

Scientists have discovered that gravitational waves could turn neutron stars into cosmic tuning forks with characteristic reverberations that reveal their interiors.

How do you dust a star for prints? Scientists have the answer to this strange question: by reconstructing the magnetic field of an infant star from the planet-forming disk of gas and dust around it.

The "dark universe detective" space telescope Euclid has discovered its first Einstein ring in the process, learning about dark matter at the heart of a distant galaxy.

New research indicates that matter ejected during the supernova death of a star can fall back to neutrons stars, giving rise to mysterious "low-field magnetars."

Black holes and soccer balls don't have much in common, but if black holes are curved when kicked, it might say something deep about the cosmos.

The chances of the asteroid 2024 YR4 hitting Earth in 2032 appear to have doubled, but an asteroid hunter explains to Space.com why this isn't cause for concern.

Using the Gemini North telescope, astronomers have detected the largest black hole jet ever seen in the early universe. It's twice as long as the Milky Way.

Using 20 years of data from the Hubble Space Telescope astronomers have discovered that turbulent stars could be corrupting observations of some exoplanets.

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a gamma-ray burst, or by something entirely new?

A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than expected.

WASP-121b is like nothing in the solar system, raining liquid metal and being puffy like a marshmallow. The origins of these "toasted marshmallow" planets could be more complicated than thought.

NASA's Juno spacecraft has spotted the most powerful volcanic eruption ever seen on the solar system's most volcanic body, the Jovian moon Io.

Scientists may have figured out how Mars hung onto its surface liquid water in its ancient history via alternating periods of hot and cold. But what would the impact have been on habitability?

By studying the fastest jet ever seen erupting from an infant star, astronomers have discovered that the mechanism that launches these jets also launch supermassive black hole jets.

Observations from NASA's Chandra X-ray telescope and the VLT have revealed jets blasting from supermassive black holes cause gas to cool and fall toward them in a cosmic feeding process.
