The Antennae Galaxies, Arp244, Corvus
Viewed amidst a field strewn with Milky Way stars, the Antennae are a pair of interacting galaxies 63 million ly away. They passed through each other a few hundred million years creating huge tidal streams of new stars which form the "antennae". The main bodies of the galaxies have partially merged triggering an incredible burst of star formation as indicated by the blue knots of young star clusters, the huge region of red emission and brown dust filaments. Eventually star formation will cease and the two galaxies will fully merge to create a large elliptical galaxy.
The bluish distorted barred spiral galaxy lower left is NGC 4027, 83 million lys distant.
