A decade after the finding of the Fast Radio Burst (FRB) in 2007, an international team of astronomers for the first time has directly traced the origin of one extreme and the intense signal from a dwarf galaxy located in the pentagon-shaped constellation Auriga. The mysterious signal of Fast Radio Burst, which over the year has kept on baffling the scientists across the world, for the first time, has been mapped out to a spot in the sky situating more than 3 billion light-years away from the earth.
Scientists previously believed the sporadic bursts of radio waves to be sourced from the Milky Way itself, or from the closest galactic neighbors of the earth. But three new cosmological studies have confirmed the new modest derivation of this unexplained burst. According to one of the three studies published in the journal Nature, the rays are radiating from a dwarf galaxy which is 1% the mass of the earth. The galaxy is positioned 3 billion light years from the location of earth and is much smaller than the mass of our planet.
To recall, FRB, for the first time, was discovered in 2007. In the same year, the scientists found some strange, strong, and intense rays sourcing in the space. Though the waves lasted just for a fraction of second but emitted extremely powerful and concentrated waves than our sun spread out in 10,000 years, which no doubt surprised the global astronomic community. In 2007, total Eighteen FRBs have been discovered, and scientists believe that one of these bursts takes place in the sky once in every 10 seconds. While previously, the scientists believe the rays coming from our Milky Ways, the new findings have corroborated the radio bursts coming from the tiny galaxy, locating trillion light years away from the earth.
As per the new study, the radio bursts known as FRB 121102 derived from the interior of a dwarf galaxy which is made for a gathering of stars and is much smaller than other large galaxies like the Milky Way.
According to Cees Bassa, a cosmologist at the Netherlands Institute for Radio Astronomy (ASTRON) and the co-author of one of the three new studies, “The finding of FRB 121102 being originated from a dwarf galaxy was truly unexpected.”
