1. Juli 2019 · In the violent world of stars, gas, and interstellar dust, most galaxies that collide merge fully into a single chaotic object. “Minor mergers, those between a large and a small galaxy,” says...
17. Apr. 2023 · A stunning smash-up of two spiral galaxies shines in infrared with the light of more than a trillion suns. Collectively called Arp 220, the colliding galaxies ignited a tremendous burst of star birth. Each of the combining galactic cores is encircled by a rotating, star-forming ring blasting out the glaring light that Webb captured ...
17. Aug. 2022 · As the stellar stuff of colliding galaxies migrates in, so will the gigantic black holes that scientists believe sit at the centers of most large galaxies. The dense, invisible objects will...

As soon as astronomers realized that there are objects that are separate from our own Milky Way, they observed some galaxies that appeared to be much messier than normal. But it wasn't immediately obvious that galaxies actually do anything as interesting as merge. After all, this fantastic physical process takes hundreds of millions of years to pla...
In this very crude and simplistic way, Holmberg could step through the eons, watching the interplay of two galaxies as they mixed and mingled via gravity. And he saw an interesting feature: An "arm" of stars reached out between the galaxies as they drew near, with a "counterarm" appearing on the opposite side of each galaxy. While the results were ...
The force of gravity is enough to distort the shapes of galaxies as they encounter one another. But galaxies themselves are mostly (relatively) empty space. Stars are just tiny little dots compared to the enormous volumes of space within a galaxy. When you think of these beasts colliding, don't imagine a car crash. Instead, think of two swarms of b...
31. Jan. 2024 · Some are fated to collide, like the Milky Way and Andromeda. Credit: NASA and J. Olmsted (STScI) Types of Galaxies. What Kinds of Galaxies Are There? Astronomers classify galaxies into three major categories: elliptical, spiral and irregular.
22. Feb. 2022 · A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope. The interacting galaxy duo is collectively called Arp 143.
31. Mai 2012 · Although the galaxies will plow into each other, stars inside each galaxy are so far apart that they will not collide with other stars during the encounter. However, the stars will be thrown into different orbits around the new galactic center.
