NGC 1365 Core (Chandra+HST)
A composite utilizing both HST and CXO data to visualize x-ray emission from the galaxy's nucleus. Its bright central supermassive black hole is actively accreting matter and the surrounding disk is glowing hot with x-rays. Star formation encircling the nucleus also heats interstellar gas to create a diffuse, nebular glow further out from the nucleus.
