Watch the face of the Sun …

You can now pick up a video or image of theSun on a weekly basis, just to see what it has been doing in the previous 7 days – www.physorg.com/print244977331.html. The Solar and Heliospheric Observatory (SOHO) is a co-operative venture between NASA and the European Space Agency (EPA) designed to study the internal structure of the Sun, its outer atmosphere and the origin of the solar wind, and the stream of ionised gas, or plasma, that blows outward throughout the Solar System.
