An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collision, one that has been ...

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 ...

Most messages are press releases about astronomical discoveries—okay, scratch that; most of them are spam, but science announcements are an easy second place. But I also get questions from readers ...

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 ...

Recently, two NASA space telescopes, the James Webb Space Telescope and Chandra X-Ray Observatory, captured images of two galaxies beginning to collide. NASA released a composite image showing both ...

NASA has released a new composite image of two spiral galaxies, NGC 2207 and IC 2163, as they begin a multi-billion-year process of merging into a single celestial entity. This event was captured with ...

(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 ...

Eleonora Troja receives funding from European Research Council. Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The ...
