The discovery offers fresh clues about cosmic evolution when the universe was barely a billion years old. However, these ...

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.

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 ...

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 ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

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 ...

Rogue black holes, drifting through the cosmos, may carry with them the rich histories of their original galaxies, acting as ...
