The sun shows a bit of flare: Stunning image shows explosion so powerful it may damage electrical grids on Earth

The largest solar flare in four years may cause spectacular Northern Lights displays over Britain

If your satnav suddenly sends you the wrong way, don’t blame your gadget’s irritating electronic voice, blame the Sun.
