Snapshot of cosmic burst of radio waves
A strange phenomenon has been observed by astronomers right as it was happening — a “fast radio burst.” The eruption is described as an extremely short, sharp flash of radio waves from an unknown source in the universe. Over the past few years, astronomers have observed a new phenomenon, a brief burst of radio waves, lasting only a few milliseconds. It was first seen by chance in 2007 when astronomers went through archival data from the Parkes Radio Telescope in Eastern Australia. Since then they have seen six more such bursts in the Parkes telescope’s data, and a seventh burst was found in the data from the Arecibo telescope in Puerto Rico. They were almost all discovered long after they had occurred, but then astronomers began to look specifically for them right as they happen. Read more. |
