What famous space discovery was made inside CTA 1?
In 2008, NASA's Fermi Gamma-ray Space Telescope discovered PSR J0007+7303 inside CTA 1. This was a groundbreaking discovery because it was identified as the first known gamma-ray-only pulsar.
When was the gamma-ray pulsar inside CTA 1 discovered?
The unique pulsar within CTA 1 was officially identified by the Fermi observatory in 2008. Before this observation, scientists had primarily detected pulsars through their radio or X-ray emissions.
Where in the night sky can you find CTA 1?
CTA 1 is located deep within the constellation Cepheus. While it cannot be seen with the naked eye, high-powered telescopes can detect the faint radio and gamma-ray emissions from this distant supernova remnant.
