SPACE-CHANDRA-BLACK-HOLES
This image obtained from NASA on August 31, 2011, is a composite of X-rays from Chandra (blue) and optical data from the Hubble Space Telescope (orange and yellow) of the spiral galaxy NGC 3393. Meanwhile, the inset box shows the central region of NGC 3993 as observed just by Chandra. Two separate peaks of X-ray emission (roughly at 11 o'clock and 4 o'clock) can clearly be seen in the inset box. These two sources are black holes that are actively growing, generating X-ray emission as gas falls towards the black holes and becomes hotter. = RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / X-ray: NASA/CXC/SAO/G.Fabbiano et al; Optical: NASA/STScI" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS =
