Astronomers combined data from NASA’s JWST and Chandra X-ray Observatory to create a stunning new image of two merging spiral galaxies ...

New observations of a pair of colliding spiral galaxies hint at what might be in store for the Milky Way and the Andromeda galaxy if and when they collide. The findings, described in July in the ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with ...

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 ...

CNN — A new telescope image showcases two entangled galaxies that will eventually merge into one millions of years from now -- and previews the eventual, similar fate of our own Milky Way galaxy. The ...

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 ...

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 ...

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 ...

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 ...

For the first time, astronomers have been able to combine the deepest optical images of the universe, obtained by the Hubble Space Telescope, with equally sharp images in the near-infrared part of the ...
