X-ray, Optical & IR Images of NGC 2207 and IC 2163
X-ray data from Chandra have revealed that NGC 2207 and IC 2163, currently in the process of colliding with one another, have produced one of the most bountiful collections of super bright X-ray lights called "ultraluminous X-ray sources" (ULXs). The true nature of ULXs is still debated, but they are likely a peculiar type of X-ray binary. In these images, X-ray data from Chandra, optical light data from Hubble, and infrared data from Spitzer are shown.
