Jupiter’s Great Red Spot goes deep—really deep

The Great Red Spot on Jupiter is a 150-year-old storm larger than Earth, but just how deep into the planet does it go? Using radio-wavelength data collected this year by NASA’s Juno mission, researchers have found that signatures of the Great Red Spot persist roughly 300 kilometers into Jupiter. That’s some deep weather: The largest storms on Earth—like hurricanes—top out at about 15 kilometers tall. These results were reported at the American Geophysical Union meeting this week in New Orleans, Louisiana.
