Solar and Heliospheric Observatory
Stationed 1.5 million kilometres away from Earth, SOHO constantly watches the Sun, returning spectacular pictures and data of the storms that rage across its surface. SOHO's studies range from the Sun's hot interior, through its visible surface and stormy atmosphere, and out to distant regions where solar wind battles with a breeze of atoms coming from among the stars. The SOHO mission is a joint ESA/NASA project.
