"Bully" black hole blasts nearby galaxy - NASA

A "death star" galaxy is sending out a powerful jet of particles and magnetic radiation that is likely obliterating any possible life in its broad path, notably in a nearby galaxy, astronomers said on Monday.

They said the two galaxies appear to be merging and the disturbance in the magnetic field caused by this movement may have awakened a dormant, supermassive black hole in one of the galaxies.

They have images of the deadly blast, spurting out from a system known as 3C321.
