On October 9, 2022, an unusually bright and long-lasting gamma-ray burst—the most powerful type of explosion in the universe—was detected by the Neil Gehrels Swift Observatory, whose Mission Operations Center is located at Penn State and led by Professor of Astronomy and Astrophysics John Nousek. The burst—the brightest ever recorded, called GRB 221009A—originated from the death of a massive star about two billion light years away, likely collapsing to form a black hole and sending gamma rays, X-rays, and other particles into space.
A striking image of the burst’s afterglow was captured by Swift’s X-Ray Telescope, which is led by Penn State Research Professor of Astronomy and Astrophysics Jamie Kennea and was originally built under the leadership of Professor of Astronomy and Astrophysics David Burrows. Swift and other observatories are continuing to observe the aftermath of the event, which could help provide new insights into stellar collapse, the birth of a black hole, and the conditions in distant galaxies.
