Interestingly, of more than 1,000 Fast Radio Bursts discovered to date, only 29 have been identified as repeating FRBs. These phenomena consist of bursts emitting more energy in one millisecond than our Sun in three days.
The universe is a mysterious place. Exploring it is no easy task. So when scientists come across something they do not understand, it is a “well, that’s a funny moment.” One of the most puzzling discoveries in the universe is the so-called Fast Radio Bursts or FRBs. We have absolutely no idea what these cosmic signals are and what produces them. But deep space exploration reveals more and more of these mysterious alien signals. With the help of a new algorithm, scientists combing through observations made by the CHIME radio telescope have come across 25 alien signals in data gathered between 2019 and 2021. The curious thing is these are not ordinary FRBs but repeating ones.
Peculiar alien signals
What makes these signals even more peculiar is that, just like gravitational waves (GW) and gamma-ray bursts (GRBs), fast radio bursts (FRBs) are one of the most powerful and mysterious astronomical phenomena discovered to this date. These phenomena consist of bursts emitting more energy in one millisecond than our Sun in three days. Interestingly, most bursts last just milliseconds, but there have been rare cases of repeated FRBs, just as the 25 that were recently identified by experts. With the help of CHIME, scientists have discovered more than 1,000 FRB sources to this day.
Repeating FRBs
Interestingly, of more than 1,000 Fast Radio Bursts discovered to date, only 29 have been identified as repeating FRBs. As explained by Universe Today, all the repetitive FRBs were found to repeat irregularly. The only exception is FRB 180915. It was discovered by CHIME researchers in 2018 (and reported in 2020) and pulsates every 16.35 days. With the help of this new algorithm, the CHIME collaboration spotted 25 new sources, doubling the number of repeating FRBs available for study.
