A recent study discovered the exact location of the Yellowstone supervolcano's magma cap -- and hints at when it may erupt.

Yellowstone's supervolcano appears to have a magma cap that vents pressure and reduces the chances of a massive eruption happening anytime soon.

A new study shows a volcanic eruption of Yellowstone may be even less likely than we thought: Scientists have discovered a magma cap that may play a role in relieving volcanic pressure underground.
