HTTP:: Even a 039 Quiet 039 Sun Affects Earth
--------
Established astronomical knowledge had it until recently that the number of sunspots on the surface of the Sun was a clear indicator of the intensity of solar winds, and therefore of the dangers that were in store for the Earth. Solar winds are known to be extremely disruptive towards our electrical systems. They can easily fry transformers and wires, and have the ability to destroy satellite networks and to jeopardize the International Space Station, as well as communications with our deep-space probes. According to ABC News, experts in the United States have determined that the planet has been bombarded with similar amounts of solar winds over the last year as the years before, which is not in tune with the theory. The Sun was unusually quiet last year, and therefore, according to estimates, it should not have emitted such intense solar winds. Astronomers from the National Center for Atmospheric Research (NCAR) and the University of Michigan (UM) were behind the new stu!
dy. “The Sun continues to surprise us. The solar wind can hit Earth like a fire hose even when there are virtually no sunspots,†NCAR High Altitude Observatory expert Dr. Sarah Gibson, who has also been the lead author of the new paper, says. Details of the finds appear in the latest issue of the respected Journal of Geophysical R...
