Astronomers continue to find stars that should be dead. Now we can finally find out why

The most massive stars in the Universe also have the shortest lifespans. The more mass a star has, the faster it burns up its fuel stores, resulting in lifespans of less than about 10 million years. This fascinating fact leads us to a riddle. Most of these stars are relatively …
