Star Clusters Born Among the Interacting Galaxies of Stephan's Quintet

This close-up view of Stephan's Quintet, a group of five galaxies, reveals a string of bright star clusters that sparkles like a diamond necklace. The clusters, each harboring up to millions of stars, were born from the violent interactions between some members of the group. The...

HubbleMinute: Battle Royale in Stephan's Quintet

Astronomers studying the compact galaxy group Stephan's Quintet have seen creative destruction in the many collisions taking place among its galaxies. This HubbleMinute discusses what astronomers are learning and hope to learn from examining the quintet.

Galactic Collision Simulation

Animation depicts the wrenching processes unleashed when two galaxies collide. This animation is a rendering of a data simulation that astronomers use to study interacting and colliding galaxies.
