... 2008 October 21 . A Dark Pulsar in CTA 1 . Credit: NASA , S. Pineault ( DRAO ) . Explanation: Where's the pulsar? Previously, the nebula CTA 1 showed an expanding supernova remnant , a jet , and a point source expected to be a pulsar -- a rotating neutron star producing pulses at radio energies. ... Now NASA's recently deployed Fermi Space Telescope has solved the mystery with some of its initial observations indicating that the point source is pulsing at gamma-ray energies . ...
