E.T. calling

Mysterious radio bursts are probably not ET calling, but never mind.

they are probably from "powerful astrophysical events".

The problem: what is an astrophysical event?

speculation varies widely on their cosmic transmitters, according to James Cordes, a radio astronomer at Cornell University in Ithaca, N.Y.
Evaporating black holes, supernovae, merging neutron stars, or neutron stars with unusually strong magnetic fields compared with other neutron stars all could be possible sources, Dr. Cordes writes in a commentary in Science tied to the new discovery.
