Second ‘Great Spot’ found at Jupiter, cold and high up

BY MARCIA DUNN

CAPE CANAVERAL, Fla. (AP) — Another “Great Spot” has been found at Jupiter, this one cold and high up.

Scientists reported Tuesday that the dark expanse is 15,000 miles (24,000 kilometers) across and 7,500 miles (12,000 kilometers) wide. It’s in the upper atmosphere and much cooler than the hot surroundings, thus the name Great Cold Spot. And unlike the giant planet’s familiar Great Red Spot, this newly discovered weather system is continually changing in shape and size. It’s formed by the energy from Jupiter’s polar auroras.

A British-led team used a telescope in Chile to chart the temperature and density of Jupiter’s atmosphere. When the researchers compared the data with thousands of images taken in years past by a telescope in Hawaii, the Great Cold Spot stood out. It could be thousands of years old.

“The Great Cold Spot is much more volatile than the slowly changing Great Red Spot … but it has reappeared for as long as we have data to search for it, for over 15 years,” the University of Leicester’s Tom Stallard, lead author of the study, said in a statement.

Stallard said Jupiter’s upper atmosphere may hold other features. Scientists will be on the lookout for them while also studying the Great Cold Spot in greater detail, using ground telescopes as well as NASA’s Juno spacecraft in orbit around Jupiter, he said.

The study was published in Geophysical Research Letters, a journal of the American Geophysical Union.
