A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

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 ...

Mid-infrared observations from NASA's James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA's Chandra X-ray Observatory, highlighted in blue. Together, ...

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

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 ...

New data confirm that the titanic collisions of galaxies ignite the most powerful active galactic nuclei. Active galactic nuclei (AGN) are phases in which supermassive black holes at the centre of ...

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 ...
