An idle astronomy game drawn around a real-time, ray-traced black hole. Point your telescope at M87*, build the observatory that reveals it, and watch every upgrade change what you see: in visible light, infrared, radio, X-rays and gamma rays.
Catch the sky's events, follow the observing programme, and move on to Sagittarius A*, Centaurus A, Cygnus X-1 and TON 618.
