The big picture: Solar wind is a stream of electromagnetically charged particles released from the upper atmosphere of the Sun, the corona, and it permeates every planet and cosmic object in the Solar System. When something changes in the amount of charged particles, unexpected and extreme atmospheric phenomena can be observed.
The system is an important step forward to harnessing fusion as a clean energy source
Forward-looking: Fusion differs from fission, which is used in nuclear power plants, and it is based on the same principle that powers the Sun and stars as the hydrogen nuclei fuses into helium, releasing light and heat. Also, unlike nuclear power, fusion is intrinsically safe in that the reaction stops when the fuel supply or power source is shut down. Nor does it generate high-level long-lived radioactive waste.
