SOHO
Providing new views of the Sun’s atmosphere and interior, and investigating the cause of the solar wind.
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 the wind from the Sun battles with a breeze of atoms coming from among the stars. The SOHO mission is a joint ESA/NASA project.
