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 ...

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 ...

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 ...

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 NASA’s Chandra X-ray Observatory and Hubble Space Telescope, researchers pinpointed a short gamma-ray burst to a faint galaxy that appears to be part of a larger group of galaxies about 8.5 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...

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 ...

At the start of cosmic history, galaxies were big clouds of gas, and they grew by turning that gas into stars. If a galaxy runs out of gas, it will stop forming stars and die. Present-day galaxies ...

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 ...

Quasars are some of the brightest objects in the universe. A quasar is powered by large amounts of matter falling into the supermassive black hole at the center of a galaxy. Collisions and mergers ...
