Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

The universe is overrun with dark matter, outweighing the ordinary stuff that stars and planets are made of five-to-one. But ...

You know that feeling when you find something hiding right where you've been looking all along? Astronomers just had that moment on a cosmic scale. A galaxy so faint, so nearly invisible that no one ...

The Hubble and Euclid space telescopes caught a stunning portrait of a dying star at the heart of the Cat's Eye Nebula.

A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...
