Mergers and Acquisitions

Arp 299 is a pair of colliding galaxies. Both of them are classified as barred irregular galaxies. The interaction of the two galaxies is producingstarburst regions. Data from the Chandra X-Ray Observatory reveals 25 bright X-ray sources in Arp 299. The image above combines X-ray data from Chandra (pink), higher-energy X-ray data from NuSTAR (purple), and optical data from the Hubble Space Telescope (white and faint brown).
