Are we safe from the sun? Solar flares keep on getting stronger - with latest hotspot the size of 15 Earths strung together
The sun is a tempestuous mistress - and her outbursts are becoming more and more violent as the weeks go on. NASA's Solar Dynamics Observatory spotted the summer's first 'X' solar flare on Friday - a huge outburst from the sun right at the top of the scale.
This came on the back of 12 'M' flares in just six days, with a M6.1 flare knocking out radio signals across the planet on Thursday - hinting at the destruction the sun could reign on our technology if Earth takes a full blast across its blow. The sunspot group behind the flares - named as AR1515 - stretches across 118,681 miles (191,000km) of the sun's surface.
This makes it's width more than 15 Earths set end to end, said NASA solar astrophysicist C. Alex Young.
