We're also going to show Jupiter some love too

Centuries ago, a massive red spot on Jupiter mysteriously disappeared, only for a new one to emerge years later.

Today, we know this striking feature as the "Great Red Spot," a storm larger than Earth. Interestingly, early astronomers like Giovanni Domenico Cassini in 1665 noted a large red storm at the same latitude on Jupiter, suggesting the possibility that they might be the same storm. However, recent research indicates otherwise. By examining historical drawings and early telescope observations, astronomers have concluded that today's Great Red Spot is a different storm from its predecessor, which was known as the "Permanent Spot." This earlier storm likely vanished between the mid-18th and 19th centuries.

Agustín Sánchez-Lavega, a planetary scientist at the University of the Basque Country in Spain, explained to Mashable that "no astronomer of the time reported any spot at that latitude for 118 years." Then, in 1831, a conspicuous red spot appeared once again. The new research, published in Geophysical Research Letters, suggests that this current spot is at least 190 years old.

This is one impressive storm, having spun counterclockwise for nearly two centuries with winds reaching up to 400 mph. Planetary scientists at NASA and other institutions are studying to understand what gives this storm its vibrant red color. Historical documentation of the Permanent Spot also reveals it was much smaller than the Great Red Spot of the 19th century and beyond, implying that it would have had to triple in size—a phenomenon never observed in a storm on Jupiter, as Sánchez-Lavega pointed out.
