First appearing as a tiny blemish on Dec. 5, 2010, the storm is still
going strong today, surpassing the ringed giant's previous longest
tempest, which lasted 150 days back in 1903. NASA’s
Cassini spacecraft, in orbit around Saturn, has given astronomers a front-seat view of this enormous maelstrom and provided valuable data.
From its humble beginnings, the storm has grown to engulf the entire
area between Saturn’s 30th and 51st north latitudes. From north to
south, the tempest stretches about 9,000 miles — greater than diameter
of the Earth — and covers two billion square miles, or eight times the
surface area of our planet.
