A strange break in a stream of stars in the Milky Way could be the result of dark matter, but only if the dark matter is hot and self-interacting.

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight rope around it.

Scientists want to know if a tidal disruption event that exploded twice is the result of a star abandoning its binary partner, allowing it to be devoured by a supermassive black hole.

The fastest-spinning white dwarf ever discovered is a shrinking cosmic vampire feasting on a stellar companion. A feeding process is pushing the dead star toward an imminent supernova explosion.

BepiColombo made its sixth and final flyby of Mercury on Wed (Jan. 8) capturing images of the tiny planet hinting at the mysteries it will soon investigate.

Interactions between dark matter and dark photons during a "missing chapter" cosmic history could shed light on one of the most troubling cosmic mysteries.

You may be stuck in the Milky Way but new research suggests the carbon that makes up your body took an intergalactic round trip on a cosmic conveyer belt.

Einstein may have been troubled enough by entanglement to call it "spooky action at a distance" but scientists have discovered it operates at small scales between quarks and gluons in protons.

Pluto may have got romantic to capture its largest moon, colliding and engaging in a passionate but icy 10 hour kiss with Charon billions of years ago.

A rare group of aligned, star-birthing dwarf galaxies resemble a cosmic string of pearls.

Celestial fireworks that erupt all year long but last a fraction of a second, fast radio bursts, may have traced them to the immediate surroundings of extreme and highly magnetic dead stars.

2024 was a big year for the study of the universe's most troubling and mysterious "ingredient," dark energy. Here's what scientists found.

2024 was a big year for black hole science, and Space.com was on duty all year to bring you every major development in our understanding of the universe's most fascinating entities.

What did you get fot X-mas? Scientists may have been gifted with a solution to the mystery of juMBOs, strange celestial bodies that seem to be neither planets nor stars.

On Christmas Eve (Dec. 24) NASA's parker Solar Probe made its closest approach to the sun yet, passing through the blisteringly hot outer atmosphere of our star.

Astronomers have accidently spotted a new type of cosmic explosion called a "millinova" triggered by white dwarfs feeding on stars. If that sounds familiar get ready for a suprise!

Using the NASA space telescopes Hubble and Chandra astronomers have discovered a strange black hole that has been knocked on its side in a cosmic crime scene.

A "missing link" black hole in Omega Centauri is still missing. What appeared to be an intermediate-mass black hole was a cluster of stellar-mass black holes.

Investigating a young exoplanet called PDS 70b in its cocoon of natal gas and dust has shown that planets don't always resemble the environments they form in.

The James Webb Space Telescope has caught a napping monster black hole in the early universe. The cosmic giant is slumbering after a massive meal like a reveller on Christmas Day.

The disagreement in the rate of expansion of the universe, the Hubble tension, could arise from the fact Earth sits in an under-dense supervoid region of space.

Astronomers have used the Very Large Telescope to discover the first binary stars around the supermassive black hole at the heart of the Milky Way.
