A Dark Pulsar in CTA 1

NASA APOD
COSMIC MESSAGE

In the CTA 1 supernova remnant, astronomers expected to find a pulsar, a rapidly spinning neutron star that emits radio waves. But no radio pulses were detected. NASA's Fermi Space Telescope, however, found the source pulsing at gamma-ray energies. This "dark pulsar" is the first of a new class of objects.
