It's Not a Comet, It's a Pulsar (http://www.universetoday.com/am/publish/not_comet_pulsar.html?2392004)


The Chandra X-Ray Observatory took this image of a pulsar surrounded by high-energy particles as it plows through interstellar space. The pulsar is hurtling to the left in this image at a speed of 2.1 million kph (1.3 million mph), and the particles are being blasted back like the tail on a comet. The pulsar is known as "The Mouse", aka G359.23-0.82, and it was discovered in 1987 by radio astronomers using the Very Large Array in New Mexico. Because it's moving so quickly and interacting so visibly with its environment, astronomers have a unique opportunity to understand pulsar magnetic fields, and how they eject material.
