Scientists have confirmed that colossal collisions between galaxies trigger titanic eruptions in the centers of those galaxies, and the discovery is thanks to an artificial intelligence tool that was ...

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

Surveying nearby galaxies in the process of merging with other galaxies, astronomers have identified massive, dense star factories, unlike any found in the Milky Way. The findings provide a rare ...

Two massive galaxy clusters are slamming into each other, and for once astronomers are not reconstructing the crash from the debris long after the fact. They have caught the system in the act, with ...

The schematic artistic view of the Cosmic Owl, consisting of twin collisional ring galaxies with binary AGN. Credit: arXiv (2025). DOI: 10.48550/arxiv.2506.10058 An international team of astronomers ...

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 ...

Examples of merging galaxies containing a heavily obscured growing supermassive black hole observed by the Hubble Space Telescope. The top panels show nearby galaxies at ~500 million light-years from ...

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 ...

Astronomers have discovered an incredibly rare system in which at least five galaxies from the early universe are merging — just 800 million years after the Big Bang. The remarkable discovery was made ...
