Combined data from Chandra (red, green, and blue) as well as optical light (light blue) and hydrogen emission (gold) reveals a microquasar in the galaxy NGC 7793. This system contains a stellar-mass black hole that is being fed by a companion star, shown in X-rays in the upper inset. Material falling onto the black hole is blowing outward via two powerful jets that plow into the surrounding gas and heat it. The lower inset shows the nebula that is being illuminated by the output from these jets.
