Look up on a dark night and the Milky Way appears as a calm band of stars across the sky. But our galaxy has a violent past. For more than 13 billion years it has grown through star formation and ...

For decades, astronomers have cast galaxy mergers as the universe’s ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt.

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 ...

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 ...
