Extreme Star Birth in Merging Galaxies

The newest image released from the Hubble Space Telescope shows the turbulent region where two galaxies are merging together. The galactic collision is known as Arp 220, and it’s one of the nearest, brightest examples of this in the sky. Hubble’s keen vision has located more than 200 massive star clusters, the largest of which is twice as big as anything we have in the Milky Way. Arp 220 should continue producing new start clusters until it runs out of gas in about 40 million years.
