In a groundbreaking revelation, astronomers have stumbled upon an ancient radio signal that dates back a staggering eight billion years. Aptly named FRB 20220610A, this enigmatic “fast radio burst” lasted a mere millisecond but unleashed an energy equivalent to what our sun emits over three decades, as stated in the esteemed journal Science.
FRBs are characterized by intense pulses of radio-frequency electromagnetic radiation. Ever since the first discovery in 2007, astronomers have detected hundreds of these celestial flashes. However, due to their ephemeral nature, most bursts vanish after mere microseconds, leaving scientists puzzled about their origin.
In the case of FRB 20220610A, scientists notably managed to accurately pinpoint its source. Dr. Stuart Ryder, an esteemed astronomer from Macquarie University in Australia, stated, “We were able to precisely identify the origin of FRB 20220610A.” According to reports by CNN, scientists believe this particular burst emerged from the merging of two or three galaxies, giving rise to the formation of new stars.
One prevailing theory suggests that these bursts are a consequence of stellar explosions. Initially detected using the Australian SKA Pathfinder, a radio telescope located in Western Australia, astronomers further employed a large-scale telescope in Chile to track down the galaxy responsible for FRB 20220610A. Interestingly, this discovery surpasses any previous findings in terms of age and distance.
The scientific community believes that FRBs could serve as a tool to gauge the universe’s weight, specifically by measuring the invisible matter located between galaxies. CNN reports that coauthor Ryan Shannon articulated, “When we take into account the amount of normal matter in the universe, we find that over half of it is missing.” He further hypothesized that this missing matter could possibly be scattered within the intergalactic regions in such a hot and diffuse state that it eludes conventional detection techniques. By sensing ionized material and visualizing electrons, FRBs enable scientists to quantify the matter present between galaxies.
Remarkably, nearly 50 FRBs have been successfully traced back to their sources, further consolidating their significance. “The frequency of FRB occurrences is truly astonishing,” commented Shannon. “It exemplifies the immense potential of this field.”
