A galactic pileup 94 million light-years away is giving astronomers a detailed look at how cosmic collisions shape the ...

A new image produced by the James Webb Space Telescope reveals new details of Stephan's Quintet, the very first compact galaxy group ever discovered. When you purchase through links on our site ...

Shockwaves resulting from the violent collision between an intruder galaxy and Stephan's Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium.

A new instrument has spotted a galaxy crashing through a group of others at incredible speeds, creating a shock wave that’s changing the region completely. Stephan’s Quintet is a structure ...

The dramatic impact was observed in Stephan's Quintet, a nearby galaxy group made up of five galaxies first sighted almost 150 years ago. It sparked an immensely powerful shock akin to a "sonic ...

Shockwaves created by a collision between the galaxies of Stephan's Quintet and an intruder galaxy are driving strange processes in the intergalactic medium, the tenuous clouds of warm-to-hot ...

Collisions like the one observed in Stephan’s Quintet are rare opportunities to study the effects of galaxy mergers. These violent interactions redistribute gas and dust, compressing them to ...

"This type of galaxy collision in Stephan's Quintet is a rare chance to see a complex set of galaxies caught in the act of colliding," Arnaudova said. "As to how it will end up, well it's likely ...

A party-crashing spiral galaxy is plowing headlong into Stephen’s Quintet at nearly 3 million kilometers per hour, causing a shock wave the size of the Milky Way. As that shock wave blasts ...

A new visualization explores the galaxy group Stephan’s Quintet by using observations in visible, infrared, and X-ray light. The sequence contrasts images from NASA’s Hubble Space Telescope ...

Stephan's Quintet includes four distant galaxies that are connected through gravity and one galaxy that is much closer to us but just happens to lie in the same direction in the sky. Public domain ...
