The Strongest Gamma Rays in Our Galaxy Are Coming From an Unknown Source!

Astronomers have discovered a mysterious bubble in the constellation Cygnus, which is keeping experts on the edge of their seats with powerful gamma-ray bursts! In contrast to the terrestrial CERN, however, this cosmic particle accelerator is also overshadowed by huge question marks – because we have no idea what kind of object we are dealing with here! The only thing that is certain is that the hidden structure produces gamma-ray photons in the order of a quadrillion electron volts – and that this makes it one of the most powerful gamma-ray sources in the entire Milky Way!
