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 ...

At the center of most large galaxies sits a supermassive black hole (SMBH). When these black holes are actively consuming ...

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 ...

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

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 ...

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 ...
