This composite image of the Crab Nebula uses data from three of NASA's Observatories. The Chandra X-ray image is shown in light blue, the Hubble Space Telescope optical images are in green and dark blue, and the Spitzer Space Telescope's infrared image is in red.
The neutron star, which has the mass equivalent to the sun crammed into a rapidly spinning ball of neutrons 20 km across, is the bright white dot in the center of the image.
