New Sun Hole Threatens Earth with High-Speed Solar Winds

A giant coronal hole, about 20 times the size of Earth, has been spotted on the surface of the sun, which could send 1.8 million mph solar winds towards Earth by Friday. Coronal holes release solar winds into space, which can damage satellites and reveal stunning auroras if they reach the Earth. Scientists aren't concerned about this particular hole damaging infrastructure, although they say it may help trigger auroras in some parts of the world.
