The Great Red Spot¶
Jupiter’s iconic Great Red Spot (GRS) is actually an enormous storm that is bigger than Earth that has raged for hundreds of years! Fig. 2 below shows an image of Jupiter captured by the Hubble Space Telescope on June 27, 2019.
Jupiter’s GRS has been observed to be shrinking for about the last century and a half! Here is some data of the length of the GRS spanning the last ~150 years which we can use to investigate this phenomenon.
