And There is More!!

The galaxy — a dwarf known as FRB 121102 that lies 3 billion light-years from Earth — is a known source of such brief, high-energy fast radio bursts(FRBs). But the newly detected pulses stand out, astronomers said.
"Bursts from this source have never been seen at this high a frequency," Andrew Siemion, director of the Berkeley SETI (Search for Extraterrestrial Intelligence) Research Center at the University of California, Berkeley, said in a statement.

Siemion is a team member with Breakthrough Listen, a $100 million project that's searching for potential signals from alien civilizations from the 1 million stars closest to the sun, the 100 galaxies nearest our own Milky Way, and the galactic plane.
Some researchers think FRBs — which were discovered in 2007 and remain mysterious today — could be such alien signals.
For example, astronomers have speculated that FRBs may be generated by powerful lasersdesigned to blast alien craft through space at high speeds — a propulsion method akin to that being developed by Breakthrough Listen's ambitious sister project, Breakthrough Starshot.
(Aliens aren't the only possible explanation, of course; some scientists think FRBs are likely emitted by fast-rotating neutron stars, for instance.)
