Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

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 ...

Will the Milky Way and Andromeda galaxies collide in several billion years? The odds have changed with a new study using 100,000 supercomputer simulations. Credit: NASA's Goddard Space Flight Center ...

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 ...

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 ...

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 ...

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 ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology. When you purchase through links on our ...
