From great to not-so-great: Jupiter's red spot shrinks to smallest size yet

One of Jupiter’s most distinctive features – the Great Red Spot – is shrinking, according to new images from the Hubble Space Telescope.

The spot, which is a violent storm, is considered to be the biggest in the Solar System. In images taken by space telescopes and probes, the storm appears as a deep red orb surrounded by layers of pale yellow, orange and white. Winds inside the storm have been measured at several hundreds of miles per hour.
