Chandra Samples Galactic Goulash
Arp 299 is a system located about 140 million light years from Earth. It contains two galaxies that are merging, creating a partially blended mix of stars from each galaxy. New data from Chandra reveals 25 bright X-ray sources sprinkled throughout the Arp 299 concoction, that astronomers categorize them as « ultra-luminous X-ray sources, » or ULXs.
