“This is the target we've been waiting for for years,” says one astrophysicist.
As dinosaurs stomped across ancient Earth more than 200 million years ago, a massive star was entering its death throes. The resulting cosmic explosion was so unusual, it left astronomers scratching their heads when its glow at last reached our planet last June.
Now, the mysterious flash may have an origin story. Based on the latest observations of the strange supernova, nicknamed the Cow, a team of 45 astronomers argues that it may represent the first time humans have captured the exact moment a dying star gave birth to a black hole.
