MYSTERIOUS 200-YEAR-OLD STORM MAY BE ABOUT TO END
A ferocious storm has battered Jupiter for at least 188 years. From Earth, it is observed as red swirling clouds racing counter-clockwise in what is known as the planet's "Great Red Spot." But after shrinking for centuries, it may now be on the brink of disappearing for good.
"The GRS will in a decade or two become the GRC (Great Red Circle). Maybe sometime after that the GRM"—the Great Red Memory.
In the 19th century, the storm was well over twice the width of Earth according to NASA.
"Think of the GRS as a spinning wheel that keeps on spinning because it's caught between two conveyor belts that are moving in opposite directions. The GRS is stable and long-lived, because it's 'wedged' between two jet streams that are moving in opposite directions."
In fact, Jupiter’s storm may have been churning for even longer than scientists know for sure. Observations dating as far back as 1665 may detail the same storm. Italian astronomer Giovanni Cassini described a “permanent spot” on Jupiter, which was observed up until 1713.
