Chandra X-ray Image of M82

Chandra X-ray Image of M82
From the Chandra X-ray Observatory
M82, at a distance of 11 million light years from the Earth, is the nearest starburst galaxy. Massive stars are forming and expiring in M82 at a rate 10 times greater than in our Milky Way Galaxy. The bright spots in the center are supernova remnants and X-ray binaries. These are some of the brightest such objects known. The luminosity of the X-ray binaries suggests that most contain a black hole. The diffuse X-ray light in the image extends over several thousand light years, and is caused by multimillion-degree gas flowing out of M82. A close encounter with a large galaxy, M81, in the last 100 million years is thought to be the cause of the starburst activity. This image was made with the Advanced CCD Imaging Spectrometer (ACIS).
