Most galaxies are expected to contain at least one massive black hole, but how robust is this prediction? New research uses ...

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.

Some massive black holes spend billions of years far from the centers of their galaxies. A new study says that these ...

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 ...

A collision may have left these galaxies without dark matter. That spells trouble for alternative gravity theories.

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 ...

At a distance of 2.5 million light years from the Milky Way, it’s hard to believe that Andromeda is our closest neighbouring galaxy. But despite the huge distance between these two elliptical entities ...
