Fast Radio Bursts. They come from galaxies far, far away, but scientists have no idea what they are.
FRBs
have mystified scientists ever since they burst onto the astronomical
scene in 2007. Since then, large radio telescopes have captured fewer
than two dozen of the enigmatic flickers, far brighter than most known
objects. Now, a pair of Harvard theorists have a wild idea: planet sized
beacons that would dwarf the Death Star, and maybe even Starkiller
Base.
Lasting mere thousandths of a second, the radio pulses are
far too bright to match what we know about other sources that emit
energy in bursts, such as the spinning neutron stars known as pulsars.
"There is no known astronomical object that generates radio bursts at such a high brightness, which is tens of billions of times brighter
than the known population of pulsars, for example," co-author of the
paper Avi Loeb of the Harvard-Smithsonian Center for Astrophysics told
