| Hubble Spies Evidence of Seasons on Neptune |
||
 Changing seasons provide some of the most spectacular scenery here on Earth. New observations from the Hubble Space Telescope provide evidence that Neptune, too, experiences seasonal weather variation. Neptune is notorious for its severe weather, including winds that can reach speeds of up to 900 miles an hour, but previous research gave no indication of changing seasons on the planet. A report published in the current issue of journal Icarus indicates otherwise. Researchers from the University of Wisconsin-Madison and NASA's Jet Propulsion Laboratory made three sets of observations of the planet over a six-year period and discovered transformations in the clouds encircling the planet's southern hemisphere. "Neptune's cloud bands have been getting wider and brighter," says Lawrence A. Sromovsky of the University of Wisconsin-Madison. "This change seems to be a response to seasonal variations in sunlight, like the seasonal changes we see on Earth." http://www.sciam.com/article.cfm?chanID=sa003&articleID=0006D94B-4E7C-1EC5-8E1C809EC588EF21 |
