"Because this burst is so bright and also nearby, we think this is a once-in-a-century opportunity to address some of the most fundamental questions regarding these explosions, from the formation of black holes to tests of dark matter models," Brendan O'Connor, a leader of teams observing the GRB said in aSpace telescopes detected the GRB, called GRB 221009A, on Oct. 9 with ground-based telescopes making followup observations of the event's aftermath.
Researchers think the GRB was triggered by a star exploding in a supernova and in the process creating a black hole 2.4 billion light-years away. The GRB was so intense scientists think it even disrupted Earth's ionosphere, affecting long-wave radio transmissions.Relatively nearby GRBs may also help scientists learn more about how elements heavier than iron — like gold and others — form in the universe.
Earlier research found these elements can form when dense neutron stars collide with one another, spreading the heavy elements across the universe.Followup observations made using the Gemini South Telescope in Chile will allow researchers to parse out more about whether those elements were created during this event, O'Connor added.
