The Sun appeared nearly featureless this weekend as the total sunspot area dropped ten times below its average value. It's all part of the normal "ups and downs" of the sunspot cycle, say scientists. Despite the low sunspot number in early May, the solar maximum is still on the way.

Two NASA scientists are working with the police and the FBI to track down criminals using out-of-this-world video technology. The new technique, called VISAR, is also expected to improve military reconnaissance, medical research and video on home computers.

An instrument on board NASA's Terra satellite recorded much less snow than usual over parts of North America during the winter of 1999-2000. This story includes a snow map of North America in March 2000 and sample pictures from Terra's snow-mapping "MODIS" instrument.

A solar eclipse is coming on Christmas Day, 2000. The winter landscape across parts of North America will assume an eerie cast, and cooler-than-usual winds might swirl, as the New Moon glides across the face of the Yuletide Sun.

As a result of the approaching solar maximum, Earth's atmosphere is puffed up like a marshmallow over a campfire. This leads to extra drag on Earth-orbiting satellites. Just last week, NASA Astronautsboosted the International Space Stationto a higher altitude to combat its orbit decay.

Earlier this month one of the most intense solar radiation storms in decades temporarily blinded NASA's Stardust spacecraft, which is heading for a rendezvous with comet Wild-2.

NASA's Hubble Space Telescope has captured dramatic images of two swirling storms on Jupiteras they collided to form a truly titanic tempest. The resulting storm may be second in size only to the Great Red Spot itself.

Two NASA satellites are seeing things beneath the cloud tops of hurricanes that have been hidden from traditional weather satellites. The new data are helping scientists understand and predict dangerous storms.
