Chandra X-ray Observations of the Crab Nebula
These images are from a sequence of Chandra observations of the Crab Nebula taken from September 2010 through April 2011. During this period, dramatic variations are seen in the Crab, including the expansion of a ring of X-ray emission around the pulsar (white dot near the center) and changes in the knots within this ring. These variations, however, did not correlate with strong gamma-ray flares seen by the Fermi Gamma Ray Observatory and Italy's AGILE satellite during that period.

Gamma-ray 'superflare' Images of Crab Nebula
Fermi's LAT discovered a gamma-ray 'superflare' from the Crab Nebula on April 12, 2011. These images show the number of gamma rays with energies greater than 100 million electron volts from a region of the sky centered on the Crab Nebula. Both views eliminate emission form the Crab pulsar by showing the sky in between its pulses. In both images, the bright source below is the Geminga pulsar. At left, the region 20 days before the flare; at right, April 14
