Seriously, though, this could be big.
Sunspot the size of Mars is turning towards Earth and massive solar flares could affect radio communications, GPS and power grids
A massive sunspot observed on the sun is turning towards Earth and is expected to increase in size over the next few days.
The area, dubbed AR2770, has a 'primary dark core' the width of Mars and a number of crater-size 'spotlets' littering its surface.
The sunspot is a member of Solar Cycle 25, the new 11-year-long period of electromagnetic activity, and was observed crackling with minor flares.
Although AR2770 has yet to produce 'killer' solar flares, experts are keeping a close watch in a bid to prepare for such an event that could knock out electrical operations and facilities on our planet.
