NASA releases spectacular X-ray image of an entire spiral galaxy

X-Rays from the Whirlpool. See Explanation: Moving the cursor over the image will bring up an alternate version. Clicking on the image will bring up the highest resolution version available.

This image combines data from four different space telescopes to create a multi-wavelength view of all that remains of the oldest documented example of a supernova, called RCW 86. The Chinese witnessed the event in 185 A.D., documenting a mysterious "guest star" that remained in the sky for eight months. X-ray images from the European Space Agency's XMM-Newton Observatory and NASA's Chandra X-ray Observatory are combined to form the blue and green colors in the image.

This image of supernova remnant 0509-67.5 was made by combining data from two of NASA's Great Observatories. Optical data of SNR 0509-67.5 and its accompanying star field, taken with the Hubble Space Telescope, are composited with X-ray images from the Chandra X-ray Observatory.
