If a galaxy runs out of gas, it will stop forming stars and die. Present-day galaxies have had more than 10 billion years to ...

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 ...

Looking ahead: Future Euclid observations will enable scientists to watch how galaxy collisions spark bursts of star formation, fuel shrouded black holes, and unleash energetic feedback. According to ...

Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than ...

Our galaxy may not collide with its neighbor after all, suggests new research. For over a century, astronomers believed a dramatic collision between the Milky Way and Andromeda galaxies was inevitable ...

Astronomers have identified a possible new example of one of the universe's strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC ...

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

A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly ...

What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how you look at it. The James Webb Space Telescope has helped two international ...

Whether or not galaxies merge depends on how strong the gravitational attraction is between the galaxies and whether the universe’s expansion is more powerful than gravity. Gravity affects everything ...

Using early data from the European Space Agency’s Euclid space telescope, astronomers have analyzed over one million galaxies to test a long-standing idea in astrophysics: that galaxy mergers help ...
