Jupiter is known for having the Great Red Spot, a massive storm that has been raging for at least 350 years. This anticyclonic storm is characterized by its reddish hue, which researchers believe is caused by complex chemical reactions in Jupiter’s atmosphere, involving ammonia and other compounds. The Great Red Spot is enormous, capable of encompassing two to three Earths, and it churns at speeds of about 432 km/h (267 mph). Observations using telescopes and spacecraft have shown that this storm is gradually shrinking yet remains a prominent feature of Jupiter's dynamic and turbulent atmosphere, drawing significant scientific interest.
