A giant hole 20 times larger than the Earth has ripped through the Sun, unleashing 1.8 million mile-per-hour solar winds towards our planet that could potentially disrupt communication channels on Friday. The gaping ‘coronal hole’ is the second to appear in one week, after the first hole was spotted on March 23. Solar activity such as this can have various impacts on the Earth, including causing auroras and disrupting power grids and satellite communications. Experts continue to study the relationship between solar activity and the Earth’s atmosphere.
