Super Star Clusters in Dust-Enshrouded Galaxy
The sharp eye of the Hubble Space Telescope's Advanced Camera for Surveys has uncovered more than 200 mammoth star clusters in the heart of the galaxy Arp 220.
The clusters are the bluish-white dots scattered throughout the image. The heftiest Arp 220 cluster - about 10 million solar masses - is twice as massive as any comparable star cluster in the Milky Way Galaxy. Arp 220 collided with another galaxy about 700 million years ago, fueling the frenzy of star birth in a small region about 5,000 light-years across. The galaxy is a nearby example of the aftermath of two colliding galaxies.
