Join us as we piece together the clues that finally unmasked the true identity of Geminga, and learn how this enigmatic object has confounded scientists for half a century. ▀▀▀▀▀▀ 00:00 Incoming Antimatter 01:59 Geminga 04:55 What Is a Pulsar? 06:32 Radio Silence 09:32 Geminga On the Move 14:54 Twin Pulsars 19:44 The Origin of Positrons 22:13 Glowing Gamma Rays ▀▀▀▀▀▀ Astrum's newsletter has launched!
