The giant star Betelgeuse may have a companion that dives straight into its outer layers. Every 2000 days, it leaves a gaseous wake, like a boat on water. Amazingly, the giant’s outer shell is cooler than the Sun, so the companion survives. This discovery reshapes our view of how stars behave before

In the Andromeda galaxy, a star faded away without a flash. James Webb and the Chandra telescope saw a dim object in a dust cocoon. This proves that a black hole can be born in the quiet collapse of a star, not just in the fire of a supernova.
