Hurricane on Saturn Would Stretch Halfway Across United States

The hurricane has wind speeds of up to 330 mph and is about 20 times larger than most hurricanes on Earth.

NASA's Cassini probe has found a "mysterious" hurricane at Saturn's north pole, with wind speeds of up to 330 miles per hour and an eye that would stretch halfway across the United States.

"We did a double take when we saw this vortex because it looks so much like a hurricane on Earth," Andrew Ingersoll, who works on NASA's Cassini project, said in a statement.

Its eye stretches 1,250 miles - approximately 20 times larger than the eyes of most hurricanes on Earth.

Unlike Earth, Saturn has no oceans, so NASA scientists think the storm is using water vapor and hydrogen to power itself.

"It is somehow getting by on the small amounts of water vapor in Saturn's hydrogen atmosphere," Ingersoll said.

While hurricanes on Earth tend to move, NASA believes that Saturn's hurricane is "locked in" at the planet's north pole. Its wind speeds are more than four times faster than strong hurricanes on Earth.

NASA's Cassini spacecraft has been monitoring the planet since 2004, but a recent change to its orbit has allowed it to monitor the planet's poles. NASA thinks the storm has been raging for many years.
