    There’s a long list of scientific discoveries that continue to puzzle researchers around the world, and one of the most mysterious comes in the form of something called Fast Radio Bursts, or FRBs. Scientists suspect that these extremely bright flashes of light originate from outside of the Milky Way Galaxy, but they still aren’t entirely sure where in the universe they’re coming from, or what kind of event causes them.


    Up until last year only 17 had been detected. That changed when the brightest FRB ever discovered was seen by two different telescopes at Parkes Observatory in Australia on August 5, 2015. Published today in the journal Science, a team of researchers from the California Institute of Technology, Curtin University, and CSIRO Astronomy and Space Science center in Australia announced not only that they’d observed the 18th FRB, but it’s also the brightest ever seen.


    Until this 18th discovery, the very first FRB ever observed also held the position for the brightest.



    When FRB 010621 was seen in 2001 at the Parkes Radio Observatory, astronomer Duncan Lorimer had no idea what to make of the signal. The 5 millisecond burst was a new kind of cosmic phenomenon, and one that sparked more questions than the field was ready for.

    Thanks for posting Paddoboy.
    Are you aware of any speculation as to possible cause?
    I wondered if it could be a signal from a major event like a BH merger... An extreme collision? A short in the electric universe?
    A compressed message from "them"
    Most interesting, thanks again... For this and all your news.

    I wonder if this means exact position or very close to...
    If exactly the same that must point us in some sort of direction... Its got to be a space beacon... where is River he could tell us.
    But how very curious.
    I will see if I can turn up more if I have time today.

    Still quite speculative as to origins as far as I know, but perhaps associated with gamma ray bursts in general and the moment of BH creation?
    [I have also heard that they maybe Aliens trying to communicate with us]

    Enterprise flashing headlights to warn us not to go over the speed limit warp 5 as there is a radar trap just behind the next planet?

    Enterprise often achieved warp 9.
    From memory there was some problem or barrier in achieving any warp higher then warp 10.
