Mysterious radio signals are so-called fast radio bursts or FRBs from some unknown source in space. Thanks to the CHIME Channel Telescope in British Columbia, astronomers have identified eight of these radio shots on Earth. FRBs are incredibly short bursts of radio waves that last only milliseconds at a time. First discovered in 2007, the FRB has caused confusion among the scientific community.
Astronomers aren't sure where FRB is coming from, but any new discovery brings us closer to solving the mystery.
A new study, previously published on the arXiv.org archive website, revealed eight new recurrent FRBs discovered in Canada.
The study states: "We announce the discovery of eight recurrent high-speed burst (FRB) sources detected using the Canadian Hydrogen Intensity Telescope (CHIME)."
PhD student at the McGuil Space Institute, Prague, Prague -authored the paper, says: "Finding eight sources like this is so important because it says we have many more recurring FRBs and can understand the environments and galaxies in which these FRBs are located if we follow them with other telescopes . "

What are fast radio bursts?
The FRB is a fairly recent discovery and remains one of the largest unknowns in the universe.
Scientists described these signals as being 1
The first FRB sign was discovered in 2007, hidden in a 2001 data set collected by the Parkes Observatory in New South Wales, Australia.
Since the discovery, astronomers have slightly expanded their understanding of FRB by learning some of the signals to be repeated.
Victoria Caspi, an astrophysicist at McGill University, tells CBC: "The first biggest conclusion is that this is not an anomalous phenomenon. This is real.
"It just takes time and patience to find them. And two, it offers the ability to locate them, and this is huge in the FRB field. "

Scientists trace repetition signals to galaxies for billions of light years, trying to are unique to no star cluster.
FRBs, for example, were traced to a galaxy in the constellation Grus at four billion light-years.
One theory suggests that radio explosions are a side effect of solid neutron stars colliding with black holes.
Another theory suggests that FRBs are produced by magnets, neutron stars with incredibly powerful magnetic fields.
Whatever the case may be, there is no clear consensus or evidence to fully unravel the mystery.
