What’s the secret to a long life? For the Great Red Spot, a massive storm that has churned on Jupiter’s surface for at least 150 years, the answer may be cannibalism.

The Great Red Spot (GRS) is about twice as wide as Earth. But over time, it’s been gradually shrinking, and the storm is currently half the size it was at the end of the 19th century. So when a string of smaller atmospheric storms collided with the GRS in recent years and caused bits of the bigger storm to “flake” off, scientists feared that the long-lived and iconic GRS might be torn to pieces.
