Astronomers discovered that pulsar PSR J002 6216 was hurtling through space at nearly 2.5 million miles an hour using data from our Fermi satellite and National Radio Astronomy Observatory (NRAO)’s Karl G. Jansky Very Large Array. Not only is the pulsar zipping through space, but it sports a radio-emitting tail pointing directly toward the expanding debris of the supernova explosion that formed it. This runaway pulsar is helping astronomers understand how supernovae are able to kick their remnan
