This composite image shows a powerful microquasar containing a black hole in the outskirts of the nearby (12.7 million light years) galaxy NGC 7793. The large image contains data from the Chandra X-ray Observatory in red, green and blue, optical data from the Very Large Telescope in light blue, and optical emission by hydrogen ("H-alpha") from the CTIO 1.5-m telescope in gold.

Nice pictures Sam.  Microquasars are fascinating and enigmatic objects and we actually have one in the northern hemisphere which is visible at this time of year.   8-)
