While 2013 is supposed to be the year of Solar Max, the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks.
After two-plus years of few sunspots, even fewer solar flares, and a generally eerie calm, the sun is finally showing signs of life.
The sun is entering its 3rd year of eerie calm. Sunspots are rare and solar flares simply aren't happening. Is this "solar minimum" lasting longer than it should? A NASA scientist has examined centuries of sunspot data to find the answer.
A new study reveals correlations between plentiful sunspots and periods of heavy rain in East Africa. Intense rainfall in the region often leads to flooding and disease outbreaks.
On July 31st, a tiny sunspot was born. It popped up from the sun's interior, floated around a bit, and vanished again in a few hours. On the sun this sort of thing happens all the time and, ordinarily, it wouldn't be worth mentioning. But this sunspot was special: It was backward.
Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
