8 billion year old radio waves reached Earth

Astronomers observe huge Radio explosion It took about 8 billion years for this light to reach Earth. It is one of the most distant and energetic explosions ever recorded, releasing the equivalent of the Sun’s total emission over 30 years.

Despite its enormous power, the explosion was called… FRB 20220610A, and lasted less than a millisecond. The source of the explosion was observed by the European Southern Observatory’s (ESO) Very Large Telescope (VLT) and found to be a cluster of two or three merging galaxies. The research was published in Science magazine.

Fast radio bursts, or FRBs, are fleeting bursts of energy that are brighter than entire galaxies and can emit as much energy per millisecond as the Sun emits in a few days. So far they have been identified About 50 such explosions.

It is still unknown what causes these huge explosions of energy, but the discovery provides new information about the distant universe. At the same time, it has been confirmed that fast radio bursts can be used to measure “missing” matter between galaxies and provide a new way to estimate the mass of the universe. It is worth noting that current methods for estimating the mass of the universe give Conflicting answers.

“If we measure the amount of natural matter in the universe – the atoms of which we are all made – we find that more than half of what should be there today is missing. “We think the missing matter is hidden in intergalactic space, but it may be so hot and diffuse that it is impossible to see with conventional techniques,” explains Swinburne University of Technology professor Ryan Shannon, one of the study’s directors. The scientist added, “Rapid bursts of radio waves detect this ionized substance.”
