A blast of radio waves hit Earth after travelling for 8 billion years

A huge burst of energy that has been travelling for more than half the age of the universe is powerful enough to microwave a bowl of popcorn twice the size of the sun

Astronomers have spotted the oldest fast radio burst (FRB) ever seen, dating back 8 billion years. Hundreds of these strange blasts of radio waves from space have now been detected on Earth since their discovery in 2007, but this one is also the most energetic ever seen.

“The burst has the energy that the sun produces in 30 years,” says Ryan Shannon at the Swinburne University of Technology in Australia. “That is enough power to microwave a bowl of popcorn about two times the size of the sun.”

Shannon and his colleagues spotted the blast of radiation, named FRB 20220610A, using the Australian Square Kilometre Array Pathfinder radio telescope and found that the FRB was three-and-a-half times as energetic as other detected FRBs.

That such things could exist for so long without dissipating into nothingness.
