Astronomers Detect 8-Billion-Year-Old Radio Signal with Extreme Energy
Astronomers have detected a radio signal originating from 8 billion years ago that contains extreme energy levels.
this “fast radio explosion,” designated FRB 20220610A, was recorded in a mere millisecond, according to the journal Science.
The electromagnetic radiation in the radio frequency range released an astonishing amount of energy,comparable to the sun’s output over 30 years.
The precise nature of these explosions is often challenging to determine due to their brief duration.
tho, scientists theorize they may stem from galactic mergers that are actively creating new stars.
These signals also offer a method to “weigh” the universe, quantifying elements between galaxies that are otherwise difficult to calculate.
Fellow author Ryan Shannon noted that a meaningful portion of the universe’s normal material, composed of atoms, appears to be missing.

Fast Radio Bursts (FRBs) are intense, millisecond-long bursts of radio waves originating from distant galaxies.Their exact cause remains a mystery, but leading theories involve highly magnetized neutron stars, or magnetars, often associated with energetic cosmic events like supernovae or black hole mergers.
The study of FRBs is crucial for understanding the intergalactic medium, the vast expanse of gas and plasma between galaxies. by analyzing how FRB signals are dispersed
