CNN Reports 8 Billion Year Old Radio Signal Reaches Earth!

"Astronomers have detected a mysterious blast of radio waves that have taken 8 billion years to reach Earth. The fast radio burst is one of the most distant and energetic ever observed.Fast radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves with unknown origins. The first FRB was discovered in 2007, and since then, hundreds of these quick, cosmic flashes have been detected coming from distant points across the universe. The burst, named FRB 20220610A, lasted less than a millisecond, but in that fraction of a moment, it released the equivalent of our sun’s energetic emissions over the course of 30 years, according to a study published Thursday in the journal Science. Many FRBs release super bright radio waves lasting only a few milliseconds at most before disappearing, which makes fast radio bursts difficult to observe. Radio telescopes have helped astronomers trace these quick cosmic flashes, including the ASKAP array of radio telescopes, located on Wajarri Yamaji Country in Western Australia. Astronomers used ASKAP to detect the FRB in June 2022 and determine where it originated. “Using ASKAP’s array of (radio) dishes, we were able to determine precisely where the burst came from,” said study coauthor Dr. Stuart Ryder, astronomer at Macquarie University in Australia, in a statement. “Then we used (the European Southern Observatory’s Very Large Telescope) in Chile to search for the source galaxy, finding it to be older and (farther) away than any other FRB source found to date and likely within a small group of merging galaxies. The research team traced the burst to what appears to be a group of two or three galaxies that are in the process of merging, interacting and forming new stars. This finding aligns with current theories that suggest fast radio bursts may come from magnetars, or highly energetic objects that result from the explosions of stars"- CNN | Posted by Thrillz
