Nasa launch spacecraft to the sun to study solar winds

Nasa is sending a robot to the sun to help understand dangerous solar activity which could threaten humanity's existence. The mission, known as the Solar Probe Plus (SPP), will go seven times closer to the sun's surface than any spacecraft before it. Nasa is launching the Solar Probe Plus (SPP) which scientists hope will unlock secrets of the sun's corona - the hole at the heart of the star It is unstable and produces solar wind and flares. Millions of tons of highly magnetized material can erupt from the sun at speeds of several million miles an hour. We need to get closer to it in order to understand how it works.
