Astronomers now believe the Milky Way's "inevitable" collision with a neighboring galaxy is much less likely than originally ...

When it comes to the Milky Way and Andromeda galaxies, there’s a whole “will they or won’t they” thing going on. In 2012 scientists published their results of Hubble Space Telescope observations ...

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 ...

Exciting new simulations reveal that our Milky Way could gracefully dodge a direct encounter with Andromeda. What once seemed ...

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 ...

Astronomers have used powerful adaptive optics technology at the W. M. Keck Observatory in Hawaii to reveal the precise locations and environments of a pair of supermassive black holes at the center ...

Water droplets on soap films orbited and merged like colliding galaxies, a technique that could help scientists study the cosmos.

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 ...

Neutron star collision in merging galaxies reveals how cosmic destruction forges heavy elements like gold, offering clues to the universe's chemical evolution. (Nanowerk News) A recently detected ...
