Photos of the Day: Feb. 19, 2014

A handout photo provided by the National Aeronautics and Space Administration (NASA) on February 18, 2014 shows an extraordinary jet trailing behind a runaway pulsar seen in this composite image that contains X-ray data from Chandra (purple), radio data from the ACTA (green), and optical data from the 2MASS survey (red, green, and blue). The pulsar - a spinning neutron star - and its tail are found in the lower right of this image. The tail stretches for 37 light years, making it the longest X-ray jet ever seen from an object in the Milky Way galaxy. The pulsar is moving away from the center of the supernova remnant (seen in the upper left of the image) where it was born at a speed between 2.5 million and 5 million miles per hour. This supersonic pace makes IGR J1104-6103 one of the fastest moving pulsars ever observed, NASA said in its accompanying press release.
