A group of galaxies, collectively know as Stephan’s Quintet recently collided creating a wonderful spectacle for astronomers.

The bright spiral galaxy was moving at two million miles per hour as it passed through the core of galaxies, which created the curved X-rays which are the light blue parts in the picture.

This image provides a rare glimpse of a galaxy group in the process of evolving and developing. It also helps astronomers understand the origins of the hot, X-ray bright halos of gas in groups of galaxies.

Don’t worry though, all this action took place 280 million light years from earth. Phew!
