2NEW Space Signals PROVE We Are NOT Alone..
Welcome back to Tech Vault. Among the newer mysteries of the cosmos are fast radio bursts, or FRBs: intense, bright blasts of radio waves from the other side of the universe that typically last just a few milliseconds. Now scientists have detected the longest-lasting FRB yet, which resembles something more like a celestial pulse than a fleeting alien blip. "It was unusual," Daniele Michilli, a researcher at MIT, recalled in a statement. "Not only was it very long, lasting about three seconds, but there were periodic peaks that were remarkably precise, emitting every fraction of a second -- boom, boom, boom -- like a heartbeat. This is the first time the signal itself is periodic."
The signal is labeled FRB 20191221A and a paper on the discovery authored by the Chime/FRB Collaboration and dozens of co-authors is published in this week's issue of the journal Nature. We've known about the existence of FRBs only since 2007, and so far FRBs that repeat or demonstrate any sort of pattern have been quite rare."This detection raises the question of what could cause this extreme signal that we've never seen before, and how can we use this signal to study the universe," Michilli says. "Future telescopes promise to discover thousands of FRBs a month, and at that point we may find many more of these periodic signals." Those signals can be used as tools to investigate even bigger mysteries, like the expansion of the universe and the life cycles of stars.
