Supermassive black holes literally don’t add up. Astrophysicists know it takes more time than is mathematically possible for ...

According to models, as supermassive black holes orbit each other, they transfer their orbital energy to the stars and gas ...

“This is the most sophisticated simulation to do this in the world right now.” ...

A violent collision between two dwarf galaxies strips them of their dark matter.

Supermassive black holes at the centers of galaxies are one of the most active fields of research in astronomy. In order to ...

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 ...

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

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 ...

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense ...

In a patch of sky about 1.2 billion light-years from Earth, astronomers have found a cosmic rarity: three galaxies caught in a merger, and all three of their central supermassive black holes are ...
