Possible Sources Include Merging Or Exploding Stars
Astronomers have detected the first population of radio bursts known to originate from galaxies beyond our own Milky Way. The sources of the light bursts are unknown, but cataclysmic events, such as merging or exploding stars, are likely the triggers. A radio burst is a quick surge of light from a point on the sky, made up of longer wavelengths in the radio portion of the light spectrum.
