May 25, 2009 - Lopsided Life After Death
Lopsided Life After Death The aftermath of the death of a massive star is shown in beautiful detail in this new composite image of G292.0+1.8. In color is the Chandra X-ray Observatory image—easily the deepest X-ray image ever obtained of this supernova remnant—and in white is optical data from the Digitized Sky Survey. A pulsar, or rapidly rotating neutron star that remained behind after the original massive star exploded, is usually found at the center of a supernova remnant. The pulsar in G292.0+1.8, however, is located slightly below and to the left of the center. Assuming that the pulsar was born at the center of the remnant, it is thought that recoil from the lopsided explosion may have kicked the pulsar in this direction, but the kick direction and the pulsar’s spin are not aligned, as they are in other remnants.
