CTB1 - Supernova Remnant
CTB 1 is a supernova remnant (SNR) in the constellation Cassiopeia and a source of optical, radio, and X-ray emissions. A recent study reports that a pulsar was born from the supernova that produced CTB 1 and ejected into the galaxy.
CTB 1 is approximately 9784 light years away and physically spans another 98 light years in diameter while it is dated to be approximately 10,000 years old.
