Jupiter's Enduring Great Red Spot

Jupiter's Great Red Spot is a storm so massive it could swallow three Earths whole.

Here's the wild part: it's been spinning nonstop for over 400 years. Scientists first

spotted it in the 1600s and it's still going strong today. The storm's winds reach 400 miles

per hour, making Earth's worst hurricanes look like gentle breezes. What keeps it alive?

Jupiter has no solid surface to slow it down, so the storm just keeps swirling through

the planet's thick atmosphere, potentially lasting for centuries more.
