Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in Boulder, Colo., ...
Scientists bid adieu to plucky solar probe
US and European scientists were Tuesday bidding farewell to the tenacious solar probe Ulysses which has been recording data around the sun for more than 18 years, four times longer than planned.
Mystery of the Missing Sunspots, Solved?
The sun is in the pits of a century-class solar minimum, and sunspots have been puzzlingly scarce for more than two years. Now, for the first time, solar physicists might understand why.
New Solar Cycle Prediction
(PhysOrg.com) -- An international panel of experts led by NOAA and sponsored by NASA has released a new prediction for the next solar cycle. Solar Cycle 24 will peak, they say, in May 2013 with a below-average ...
New Solar Cycle Prediction: Fewer Sunspots, But Not Necessarily Less Activity
(PhysOrg.com) -- An international panel of experts has released a new prediction for the next solar cycle, stating that Solar Cycle 24 will peak in May 2013 with a below-average number of sunspots. Led by ...
Warning: Sunspot cycle beginning to rise
(AP) -- When the sun sneezes it's Earth that gets sick. It's time for the sun to move into a busier period for sunspots, and while forecasters expect a relatively mild outbreak by historical standards, one ...
