Many people think that Giovanni Cassini was the first to observe the red spot in the early 1600s, but scientists doubt that the spot had just formed at that time. Jupiter's Great Red Spot was actually discovered in 1664 by Robert Hooke.
The first record of the Great Red Spot is a drawing made in 1831 by Samuel Heinrich Schwabe
Pictures of the spot allowed astronomers to see different colors in clouds around the Great Red Spot, which tell that the clouds swirl around the spot at different altitudes. The clouds move counter-clockwise.
The spot itself is an 'anti-cyclonic' (high pressure) storm on Jupiter that can be compared to the worst hurricanes on Earth. The spot is big enough to fit 2 or 3 planets of Earth's size.
