Light from the supernova explosion that gave birth to it would have first reached Earth some 1,700 years ago. The magnetized, 20 kilometer-diameter neutron star (http://imagine.gsfc.nasa.gov/docs/science/know_l1/pulsars.html) spins 7 times per second, a cosmic dynamo (http://chandra.harvard.edu/chronicle/0201/vela.html) that powers a wind (http://antwrp.gsfc.nasa.gov/apod/ap081227.html) of charged particles. The energetic wind creates the surrounding nebula's X-ray glow (http://chandra.harvard.edu/edu/xray101/xray101.html) in this tantalizing image (http://chandra.harvard.edu/photo/2009/b1509/) from the Chandra X-ray Observatory. Low energy X-rays are in red, medium energies in green, and high energies in blue. The pulsar itself is in the bright central region. Remarkably, the nebula's tantalizing, complicated (http://arxiv.org/abs/astro-ph/0504108) structure resembles a hand. PSR B1509-58 is about 17,000 light-years away in the southern constellation Circinus (http://en.wikipedia.org/wiki/Circinus). At that distance the Chandra image spans 100 light-years
