Chandra Reveals Shock Heated Gas in Colliding Galaxies January 28, 2014 A composite image of the colliding galaxies NGC6240; X-ray emission is purple and optical emission is white. Astronomers have discovered X-ray evidence for shock-heated gas moving at speeds of about 2200 kilometers per second, presumably associated with ejecta from supernovae.
