Chandra X-ray Observatory image of M82, shows the result of star formation on overdrive. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those when the Universe was much younger with lots of stars forming. M82 is a starburst galaxy, where stars are forming at rates that are tens or even hundreds of times higher than in a normal galaxy. Astronomers think that a brush with its neighbor galaxy M81 millions of years ago set off this torrent of star formation. M82 is seen nearly edge-on with its disk crossing from about 10 o'clock to about 4 o'clock in this image from Chandra (where low, medium, and high-energy X-rays are colored red, green, and blue). Among the 104 point-like X-ray sources in the image, eight so far have been observed to be very bright in X-rays and undergo clear changes in brightness over periods of weeks and years. Only a handful of such binary systems are known in the Local Group of galaxies containing the Milky Way and M31. Chandra observations are also important in understanding the rapid rate at which supernovas explode in starburst galaxies like M82. Release date January 13, 2011.
