![]() ![]() ![]() The exact origin and cause of the FRBs is still the subject of investigation proposals for their origin range from a rapidly rotating neutron star and a black hole, to extraterrestrial intelligence. ![]() When the FRBs are polarized, it indicates that they are emitted from a source contained within an extremely powerful magnetic field. In June 2021, astronomers reported over 500 FRBs from outer space detected in one year. Most FRBs are extragalactic, but the first Milky Way FRB was detected by the CHIME radio telescope in April 2020. Only one FRB has been detected to repeat in a regular way: FRB 180916 seems to pulse every 16.35 days. Many FRBs have since been recorded, including several that have been detected to repeat in seemingly irregular ways. The first FRB was discovered by Duncan Lorimer and his student David Narkevic in 2007 when they were looking through archival pulsar survey data, and it is therefore commonly referred to as the Lorimer Burst. While extremely energetic at their source, the strength of the signal reaching Earth has been described as 1,000 times less than from a mobile phone on the Moon. Astronomers estimate the average FRB releases as much energy in a millisecond as the Sun puts out in three days. ![]() In radio astronomy, a fast radio burst ( FRB) is a transient radio pulse of length ranging from a fraction of a millisecond, for an ultra-fast radio burst, to 3 seconds, caused by some high-energy astrophysical process not yet understood. Astronomical high energy transient pulse Lorimer Burst – Observation of the first detected fast radio burst as described by Lorimer in 2006. ![]()
