description Overview

CTA 1

CTA 1 is a celestial supernova remnant located in the northern constellation of Cepheus, first identified through radio astronomy surveys. The remnant hosts the neutron star PSR J0007+7303, which the Fermi Gamma-ray Space Telescope identified in 2008 as the first known gamma-ray-only pulsar. Unlike typical pulsars that emit radio waves, this object is radio-quiet and pulses exclusively in high-ene...
