Scientists from all over the world are still watching the gamma-ray burst that was first seen on October 9th.
Astrophysicist Brendan O'Connor told AFP that after the star goes supernova and collapses into a black hole, matter condenses into a disc around the black hole, falls in, and is ejected in a jet of energy that travels at almost the speed of light. He added that the flash released photons with an unparalleled 18 teraelectronvolts of energy, or 18 followed by 12 zeros. and this has disrupted long-wave radio communications in Earth's ionosphere.
In the 1960s, US satellites meant to monitor if the Soviet Union was detonating weapons in orbit discovered such bursts originated from beyond the Milky Way, marking the beginning of gamma-ray studies.
Sunday morning Eastern time observatories picked up on a gamma-ray burst now known as GRB 221009A.
Astronomers have a once-in-a-lifetime chance to gain new insights into phenomena such as black hole creation by seeing the event now, which is like watching a 1.9 billion-year-old video of those events unfold before us.
In the next weeks, O'Connor and others will keep an eye out for the telltale signs of supernovas at optical and infrared wavelengths, confirming whether or not their assumptions about the flash's origins are true and whether or not the event is consistent with known physics.
