Dr. Pierre Martin and his team created an animation showing two galaxies colliding more than 440 million years ago.

Astronomers have spotted the most distant and brightest "space laser" ever seen, blasting out from a distant galaxy collision ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

Two space telescopes really are better than one. This month NASA released a new image that combines observations from the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory of two ...

Astronomers detect a laser-like signal coming from colliding galaxies 8 billion light-years away. A cosmic mystery.

CNN — Although it looks a bit like an eerie, floating face suspended in space, the optical illusion spotted by the Hubble Space Telescope is really the result of two galaxies colliding. Hubble took ...

We learned that the stellar collision it came from was likely caused by an even more catastrophic encounter—a merger between two galaxies. This is the first time astronomers associated this type of ...

(THE CONVERSATION) 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 ...
