Vast reservoir of gas may fuel star creation in our galaxy

The Milky Way may have found a solution to its gas shortage. Astronomers had calculated that our home galaxy possesses only enough fuel to forge new stars for just a few billion more years. But scientists have now discovered that a long stream of gas falling into the Milky Way is four times as massive as previously thought and could power our galaxy’s starmaking career for a long time to come.

“It’s a very beautiful study with surprising results,” says Leo Blitz of the University of California, Berkeley, an astronomer who was not part of the project.
