The most powerful solar flare of the summer so far erupted from the sun Friday (July 6), the latest in a string of powerful storms this week from our nearest star, space weather experts say.

The sun is waking up from a long quiet spell. Last week it sent out the strongest flare for four years – and scientists are warning that earth should prepare for an intense electromagnetic storm that, in the worst case, could be a “global Katrina” costing the world economy $2,000bn.

A Japanese spacecraft has spotted two huge holes in the sun – gateways for solar material and gas to spill out into space.
Scientists call the sun holes "coronal holes." They are gaps in the sun’s magnetic field which make a hole through the star’s super-hot outer atmosphere – the corona – allowing gas to […]
Only two days ago the sun was blank and calm, displaying the sort of unrelenting quiet we’ve come to expect from the deepest solar minimum in a century. Then, with startling rapidity, sunspot 1024 burst onto the scene: movie. Unlike other recent "sun-specks", this active region is a full-fledged sunspot group with more than […]
June 17, 2009: 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.
At an American Astronomical Society press conference today in Boulder, Colorado, researchers announced that a jet stream deep inside the […]
