Astronomers have discovered an eight-billion-year-old radio signal.
The mysterious “fast radio burst” — identified as FRB 20220610A — lasted only a millisecond, but released the amount of energy our Sun emits over three decades. According to the journal Science.
An FRB is a pulse of radio-frequency electromagnetic radiation. The first was discovered in 2007 and hundreds of these cosmic flashes have been detected.
Many of these bursts last for microseconds before fading away, making it difficult to identify where they are coming from.
However, scientists were able to “precisely” determine where FRB 20220610A came from, astronomer Dr. Stuart Ryder of Macquarie University in Australia said in a statement.
Scientists believe that two or three galaxies exploded from merging and forming new stars. CNN reported.
One theory among scientists is that these explosions are the result of exploding stars.
FRB was detected early The Australian SKA uses Pathfinder, a radio telescope in the state of Western Australia.
Astronomers used a large telescope in Chile to “search for the source galaxy” and found it to be older and farther away than any other FRB seen before.
According to CNN, scientists believe that FRBs can be used to “weight” the universe by measuring the matter between galaxies that is unaccounted for.
“If we calculate the amount of ordinary matter in the universe — the atoms we’re all made of — more than half of what should be there today is missing,” said co-author Ryan Shannon.
“We think the missing material is hidden in the space between galaxies, but it may be too hot and diffuse to see using normal techniques.”
FRBs can “sense” ionized matter and “see” electrons, Shannon said, allowing scientists to “measure how much matter is between galaxies.”
According to CNN, nearly 50 FRBs have been traced from their points of origin.
“It’s surprising that FRBs are so common,” Shannon said.
“It shows how promising the field can be.”
