On June 25, 2021, Arizona astrophysicist Feryal Ozel posted an item on Twitter that must have fired up scientific imaginations. She noted that the Open Science Pool (OSPool) just set a single-day record of capacity delivered — churning through more than 1.1 million core hours. Her team’s project was leading the surge.
“Can you tell something is cooking?” she asked cheekily.
Almost a year later, the secret is out. The Event Horizon Telescope (EHT) Project, a collaboration of more than 300 astronomers around the world, announced on May 12 it had produced an image of a supermassive black hole at the center of the Milky Way, only the second image of its kind in history.
EHT made that initial history in 2019 when it shared a dramatic image of a black hole at the center of the M87 galaxy, 55 million light-years from Earth, thereby taking black holes from a theoretical concept to an observable phenomenon.
