 'Great Cold Spot' found on Jupiter twice the size of Earth
UK-based astronomers have discovered a dark cold spot on Jupiter, equalling the scale of the planet's famous 'Great Red Spot'. The newly found 'Great Cold Spot' is twice the size of Earth measuring up to 24,000 km in longitude and 12,000 km in latitude. The spot, believed to be formed by Jupiter's magnetic fields, is 200ÂºC cooler than surrounding atmosphere.
