Hubble Reveals Jupiter's Great Red Spot Is Oscillating Unpredictably

New observations show the iconic storm is changing size and shape, challenging previous understandings of its stability.

NASA's Hubble Space Telescope captured the Great Red Spot's oscillations over a 90-day period, revealing unexpected changes in size and shape.
The storm, known for its long-standing stability, is now observed to jiggle and squeeze like a stress ball, with no current hydrodynamic explanation.
Researchers found the storm's core brightens at its largest size, suggesting variations in atmospheric haze absorption.
The Great Red Spot is trapped between jet streams on Jupiter, which influence its movement and may contribute to its oscillation.
Scientists predict the storm will continue to shrink and eventually stabilize, offering insights into planetary meteorology.
