A huge ‘hole’ about 20 times the size of Earth has torn through the Sun, the second in less than a month. This gaping ‘coronal crater’ is hurling 1.8-million-mile-per-hour solar gusts towards Earth, which will hit us this Friday or Saturday. Coronal holes are a frequent characteristic of the Sun, though they show up in various locations – especially near the poles – and with greater regularity at different periods of the Sun’s solar cycle.
