NASA has spotted a huge hole in the Sun and experts have warned it could cause radio blackouts on Earth, knock out communications satellites and create radiation storms.

The sunspot, called AR2665, is 74,560 miles (120,000 kilometres) wide and big enough to be seen from Earth. NASA’s Solar Dynamics Observatory first detected the huge spot last week and experts believe it could send ‘M-class’ solar flares down to us on Earth.
