Powerful Gamma Ray Burst Hit Earth - The Outburst Shocked Astronomers
Astronomers have never seen anything quite like it. On Oct. 9, 2022, Earth-orbiting satellites detected the strongest gamma-ray burst (GRB) in modern history: GRB221009A. How strong was it? It caused electrical currents to flow through the surface of our planet. Dr. Andrew Klekociuk in Tasmania recorded the effect using an Earth Probe Antenna. Researchers have known since 1983 that gamma-ray bursts can ionize Earth’s atmosphere and, thus, disturb the great waveguide. This appears to be the first time anyone has recorded the effect using an Earth Probe Antenna. The outburst on Oct. 9th shocked astronomers. “In our research group, we’ve been referring to this burst as the ‘BOAT’, or Brightest Of All Time, because when you look at the thousands of bursts gamma-ray telescopes have been detecting since the 1990s, this one stands apart,” says Jillian Rastinejad, an astronomer at Northwestern University who has been monitoring the burst’s afterglow using the Gemini South Telescope in Chile. Researchers have since pinpointed the burst. It came from a dusty galaxy 2.4 billion light years away, almost certainly triggered by a supernova explosion giving birth to a black hole. This is actually the closest GRB ever recorded, thus accounting for its extreme intensity. https://spaceweatherarchive.com/2022/... Thanks for watching!
