On April 10, 2024, the Asteroid Terrestrial-impact Last Alert System (ATLAS) detected first light from an explosion of a massive star with roughly 12 to 15 times the sun’s mass. Just 26 hours later, astronomers pointed the Very Large Telescope (VLT) in Chile at the supernova, as this early and brief window provided a rare opportunity to study the initial phase of a star’s death.
