What is that red spot on Jupiter's surface? Fact 53

Jupiter's most distinctive feature is a giant red spot that can be seen on its surface. At its widest point, the diameter of the spot measures three times that of Earth. The spot is in fact a giant gas hurricane that has been raging for up to 350 years! The winds reach incredible speeds, up to 360 Km/h. In 1990, a satellite called the Hubble Space Telescope was launched into orbit around Earth. Since then Hubble has sent pictures to Earth of two more red dots on the surface of Jupiter.
