That close pass triggered intense star formation, which astronomers have described as "fireworks." Whenever two galaxies ...

What does it look like when galaxies collide? The Hubble Telescope captured a unique sight as two galaxies are in the process of merging. NASA says the galaxy, called NGC 1614, is about 200 million ...

Imagine two galaxies crashing into each other at mind-blowing speeds—sounds like something straight out of a sci-fi movie, right? 🚀 Well, astronomers have actually spotted a hypersonic galaxy ...

What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how you look at it. The James Webb Space Telescope has helped two international ...

Formed through the extremely unusual collision of two rare ring galaxies, the structure also serves as a natural laboratory where researchers can study many of the processes accompanying the evolution ...

In this combination of images from NASA/ESA shows three future scenarios for Milky Way & Andromeda encounter. Top left: Galaxies bypass at 1 million light-year separation. Top right: At 500,000 ...

Why it's so special: Galaxy clusters act as a magnifying lens, shining light on the faintest and most distant objects — a phenomenon known as gravitational lensing. On the rarest of occasions, galaxy ...

Astronomers have used powerful adaptive optics technology at the W. M. Keck Observatory in Hawaii to reveal the precise locations and environments of a pair of supermassive black holes at the center ...

When two pairs of galaxy clusters collide, the final result is not four separate objects, but one giant galaxy cluster. Astronomers using data from NASA's Chandra X-ray Observatory and several other ...
