    Surprise! Monster Burst of Radio Waves Arose in Tiny Galaxy

    By Calla Cofield, Space.com Staff Writer | January 4, 2017 01:00pm ET

    For the first time, scientists have directly traced an incredibly intense, blindingly bright burst of radio waves — known as an FRB — back to its home galaxy. Surprisingly, this impressive cosmic radio flasher has somewhat humble origins, according to three new studies detailing the findings.

    FRB stands for “fast radio burst.” These flickers of light were just discovered in 2007, and although they last for just a fraction of a second, they release more energy than our entire sun will radiate in 10,000 years. Eighteen FRBs have been detected, but scientists estimate that one of these bursts occurs somewhere in the sky about once every 10 seconds.

    The new study shows that the burst, known as FRB 121102, originated about 3 billion light-years away from Earth, from inside a dwarf galaxy — a collection of stars much smaller than large galaxies like the Milky Way.

    A surprising source

    The fact that FRB 121102 originated from a dwarf galaxywas a bit unexpected, said Cees Bassa, an astronomer at the Netherlands Institute for Radio Astronomy (ASTRON) and a co-author of one of the three new studies.

    “We were not sure what to expect, but I think the whole team was surprised to see that our exotic source is hosted by a very puny and faint galaxy,” Bassa said in a statement from the Max Planck Institute for Radio Astronomy in Bonn, Germany (where some of the co-authors are based).

    1. Hmm, you post this just as Octafish

    Mentions all the praise coming to Megyn Kelley of Fox from everywhere in the Top Journo Sphere.

    So I wonder if folks in that distant galaxy were Megyn fans.   ;-)

    2. That is kind of strange. Lots of energy, very fast, in small packets.
