Astronomers are stumped by a set of quick bursts of radio energy detected from outside the Milky Way Galaxy.
The Parkes Radio Telescope surveying the sky has detected the bursts, which last fewer than five milliseconds, reports Ars Technica.
There is no repeat of the events, and they have nothing accompanying them at optical X-ray wavelengths. But observing their properties shows they originate large distances from our galaxy and are the result of cataclysmic events, Ars Technica reports.
