The Hubble Space Telescope has captured a spectacular new image of one of the most dramatic events in the universe—the collision of two galaxies.

This epic galactic merger, called NGC 6052, is located 230 million light years from Earth in the constellation Hercules. It was first spotted by astronomer William Herschel on June 11, 1784, who thought it was a single oddball galaxy with an exceptionally strange shape.
