The problem is that splitting water takes more [...]
This illustration shows a CME blasting off the Sun’s surface in the direction of Earth. This left portion is composed of an EIT 304 image superimposed on a LASCO C2 coronagraph. Two to four days later, the CME cloud is shown striking and beginning to be mostly deflected around the Earth’s magnetosphere. The blue paths [...]
ScienceDaily (Sep. 1, 2010) — A new method of predicting solar storms that could help to avoid widespread power and communications blackouts costing billions of pounds has been launched by researchers at the University of Bradford. Solar storms involve the release of huge amounts of hot gas and magnetic forces from the surface of the [...]
