The Fermi Gamma-ray Space Telescope orbits the earth every 95 minutes. It travels a varied path -- north and then to the south, on alternate orbits -- in order to survey the sky with its Large Area Telescope. The picture above, courtesy of the Fermi scope, depicts the path of the Vela Pulsar, a neutron star. The plot spans 180 degrees and tracks Vela's position from August 2008 through August 2010.

Below, recent Pictures of the Day:
