A massive collision of galaxies detected

This dramatic event occurred in nearby galaxy group.

A powerful telescope has captured an unprecedented view of a massive galaxy collision in Stephan’s Quintet, a nearby galaxy group discovered nearly 150 years ago. One of the galaxies, traveling at 2 million mph (3.2 million km/h), collided with another, creating a powerful shockwave similar to a “sonic boom from a jet fighter.” This dramatic event is one of the most striking phenomena observed in the universe, showcasing the intense dynamics of galaxy interactions.
