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

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...

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.

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

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 ...
