Scientists in the Cherenkov Telescope Array (CTA) consortium have detected gamma rays from the Crab Nebula using a prototype Schwarzschild-Couder Telescope (pSCT), proving the viability of the novel telescope design for use in gamma-ray astrophysics. The results were announced June 1 at the 236th meeting of the American Astronomical Society (AAS).
