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 ...

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 ...

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 ...

Going back to our ball example, you can see that if you have 100,000 galaxies all moving towards the same destination, the odds are that some, if not most of them, are going to collide with each other ...

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 the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers may have uncovered new clues about a longstanding mystery in galaxy evolution: why ...

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 ...

A university study in Florida challenges the leading explanation for why galaxies stop forming stars. For decades, ...

Just 1.4 billion years after the Big Bang, galaxies were expected to be small, chaotic, and still forming stars. Instead, astronomers have found enormous, mature-looking systems that appear to have ...

NASA has just given us 16 more reasons to stare at the universe instead of answering our emails. Scientists have released a dazzling new gallery of galaxies that NASA is calling “cosmic gems.” The ...
