POWERFUL GAMMA-RAY BURST MADE CURRENTS FLOW IN THE EARTH: Astronomers have never seen anything 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:

Most powerful gamma-ray burst ever seen could help reveal how black holes are born
"We're just really in awe of this event and feeling very lucky to be able to study it."
All eyes are on the source of the record-breaking gamma-ray burst that lit up the sky last week.
On Oct. 9, a beam of light more energetic than astronomers had ever seen zipped past our planet, temporarily blinding detectors on several NASA satellites. The beam came from a gamma-ray burst, the most energetic type of explosion known to occur in the universe (apart from the Big Bang), which is believed to accompany the birth of some black holes.
Within hours, dozens of telescopes all over the world were pointing in the direction of the burst's source, confirming that this, indeed, was one for the books. The event, officially named GRB221009A, has since earned the nickname BOAT ("brightest of all time"), and astronomers hope it will help shed light on the mind-boggling physics behind these cataclysmic phenomena.

Bright, powerful burst of gamma rays detected by multiple telescopes

Multiple space and ground-based telescopes witnessed one of the brightest explosions in space when it reached Earth on October 9. The burst may be one of the most powerful ever recorded by telescopes.
Gamma-ray bursts, or GRBs, are the most powerful class of explosions in the universe, according to NASA. Scientists have dubbed this one GRB 221009A, and telescopes around the world continue to observe its aftermath.

Astronomers witness 'teenage' years of our universe in explosion
“The exceptionally long GRB 221009A is the brightest GRB ever recorded and its afterglow is smashing all records at all wavelengths,” said Brendan O’Connor, a doctoral student at the University of Maryland and George Washington University in Washington, DC, in a statement.
