Scientists had assumed that the ice in space was purely amorphous, but new experiments show it can have a partly crystalline structure similar to ice on Earth.

"You can think of it as a cosmic pool game. We might miss the pocket if we don't consider all the variables."

Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

The astronaut was able to capture the lake reflecting direct sunlight at the camera.

The discovery of a monster-sized black hole in a pristine galaxy unspoiled by stellar death suggests growth via mergers between primordial black holes formed during the Big Bang.

The "Hubble tension," one of the most frustrating and lingering problems in science, could be solved if Earth and the Milky Way sit in a low-density void.

The European Southern Observatory has captured the clearest images yet of the interstellar visitor 3I/ATLAS as it moves inward through the solar system.

Radar signals from "leaky" civilian and military aviation systems could act as a beacon to alien life, revealing intelligent life on Earth while helping us pinpoint them.

Astronomers use algorithms to analyze the numerous images coming from space, but how accurate are they?
