Since 2007, astronomers have been discovering very brief, strong signals from across the cosmos in observations gathered by radio telescopes. In the past week, researchers pointed the location of a non-repeating signal for the first time, and two days later, another group introduced they’d found nine more. The sources of those so-called “fast radio bursts” (FRB) remains a mystery; however, very recently, researchers have been honing their capacity to localize their origins.
On Tuesday, a crew using Owens Valley Radio Observatory (OVRO) near Bishop, California reported that it managed to capture a new, non-repeating Fast Radio Bursts dubbed FRB 190523 and hint it back to a galaxy nearly 8 billion light-years away.
Numerous possible explanations for what causes Fast Radio Bursts have been proposed, ranging from influential neutron stars to extra-terrestrial intelligence.
An accelerated article preview of the Owens Valley Radio Observatory discovery was printed online within the journal Nature, within the than a week after an Australian team working with the Australian Square Kilometre Array Pathfinder (ASKAP) introduced they’d additionally traced a non-repeating burst back to its supply galaxy, some 4 billion light-years away.
“This discovering tells us that every galaxy, even a run of the mill galaxy like our Milky Way, can generate an FRB,” says the lead author of the new paper in Nature, in a launch.
the author additionally says future radio telescope arrays like the Deep Synoptic Array set to open in 2021 will permit researchers to catch and trace many more Fast Radio Bursts.
“Astronomers have been chasing (Fast Radio Bursts) for a decade now, and we are lastly drawing a bead on them. Now we’ve got a chance of figuring out just what these exotic objects might be.”
Regardless of the source turns out to be, it is worth remembering that the mysterious signals traveled billions of years to reach here, so if the explanation is aliens, they’re some very ancient aliens.
