| Fermi Epicycles: The Vela Pulsar's Path (May 4, 2012) |
Taken with the
Fermi Gamma-ray Space Telescope, which orbits the Earth every 95 minutes and precess every 54 days, this image is a compilation of images from August 2008 to August 2010. The telescope traces the patterns of the path taken by gamma-ray sources. This particular one happens to be the Vela Pulsar. The Vela Pulsar was born from the death of a massive star in our galaxy, and is a neutron star that spins 11 times a second. It is the brightest persistent source in the gamma-ray spectrum in the sky.
