Conversation with Michael MacFerrin, Research Glaciologist Science News The Climate Lounge Pub Quiz Science News with Nevena Hristozova and Chris MacAlister An Origin of Cosmic Rays Discovered In a galaxy far far away… For real though - it’s really far - 4 billion light-years away. My calculations show that with the current tech for space flight we have, we could get there in 76.32 trillion years so it is freaking far! But anyway, the point is that this galaxy is a blazar - a type of an active galactic nucleus with a relativistic jet directed very nearly or directly towards Earth. These jets are essentially ionized matter traveling at nearly the speed of light. Relativistic beaming of electromagnetic radiation from the jet makes blazars appear much brighter than they would be if the jet were pointed in a direction away from the Earth. So far we knew that blazars are powerful sources of emission across the electromagnetic spectrum and are  sources of high-energy gamma ray photons. Now though we know somethi
