Quasar, source of radio waves, first observed in the early 1960s by CALTEC, and proposed, in 1963, by N. S. Kardashev in the Astronomical Journal of the USSR as evidence of a Type Two or Three Kardashev civilization. A worldwide sensation followed CTA-102

The quasar CTA 102 (QSO 2230+114) was observed four times in 1991-1992 by the EGRET high-energy gamma ray telescope on the Compton Gamma Ray Observatory satellite. In the 1992 January 23 -- February 6 observation, emission was detected at the level (2:4 \Sigma 0:5) \Theta 10 \Gamma7 photons cm \Gamma2 s \Gamma1 (E ? 100 MeV).
