In observations gathered by radio telescopes, Astronomers have been finding very concise and powerful signals since 2007. Last week, researchers pinpointed the site of a non-repeating signal for the first time. Then two days later, one more group announced they had discovered nine more. The sources of these FRB (fast radio bursts) remain a mystery, but in recent times researchers have been sharpening their aptitude for localizing their origins.
A team using CalTech’s OVRO (Owens Valley Radio Observatory) on Tuesday, near Bishop, California reported that it managed to capture a new, non-repeating dubbed FRB 190523 and trace it back to a galaxy almost 8 billion light years away.
An article related to the preview of OVRO discovery was published online less than a week after an Australian team working with the ASKAP (Australian Square Kilometre Array Pathfinder) declared that some 4 billion light years away they had also traced a non-repeating burst back to its source galaxy.
Moreover, a batch of nine more FRBs reported by a Russian observatory, including a new repeater. Repeating FRBs are a type of a big deal as they are rare and very easy to mark out to a source galaxy.
CalTech’s Vikram Ravi, lead author of the new paper in a release said that ‘this finding tells us that every galaxy even a run-of-the-mill galaxy such as our Milky Way, can produce an FRB’. He also said that the future radio telescope arrays in 2021 such as the Deep Synoptic Array set to open will let researchers to catch as well as trace many more FRBs.
It is worth remembering that the inexplicable signals traveled billions of years to reach us so if the clarification is aliens, they’re some extremely ancient aliens.
