Astronomers realized the event was taking place when NASA's Fermi Gamma-ray Space Telescope, Neil Gehrels Swift Observatory, and Wind spacecraft, as well as others, detected a wave of X-rays and gamma rays passing through the solar system. They called the event the GRB 221009A, and it made for an unexpectedly exciting start to the 10th Fermi Symposium, now underway in Johannesburg, South Africa. 'It's safe to say this meeting really kicked off with a bang – everyone's talking about this,' said Judy Racusin, a Fermi deputy project scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, who is attending the conference.
