Jupiter's Great Red Spot Exhibits Unprecedented Oscillations in Size and Speed

NASA's Hubble Space Telescope reveals a 90-day rhythmic cycle in the Great Red Spot, challenging previous assumptions about its stability.

Recent Hubble observations have shown the Great Red Spot 'jiggling like gelatin,' with its size and speed fluctuating unexpectedly over a 90-day cycle.
The storm's core becomes brightest in ultraviolet light when the spot reaches its maximum size, indicating changes in the upper atmosphere's haze absorption.
Researchers have noted a correlation between the storm's oscillation in size and its drift rate, suggesting complex interactions with Jupiter's surrounding jet streams.
The Great Red Spot's behavior does not conform to the known Kida relation, suggesting a more intricate internal structure and dynamics than previously understood.
Scientists speculate that the storm may eventually stabilize in size, potentially fitting within Jupiter's wind bands, but the exact cause of these oscillations remains unknown.
