A Vulcan Centaur rocket successfully launched two U.S. spy satellites on Feb. 12 despite suffering an anomaly with one of its solid rocket boosters, echoing the result of an October 2024 mission.
Four years ago, astronomers spotted a distant supermassive black hole swallowing an entire star. The star had wandered to close to the SMBH, and the black hole's powerful gravity prevented its escape. It was a tidal disruption event (TDE), and now, four years later, the energy output from the TDE is still rising.
