SOHO
Solar and Heliospheric Observatory |
|
Launched on December 2, 1995, SOHO was designed to study the internal structure of the sun, its outer atmosphere, and how the solar wind is generated. Solar flares, Coronal Mass Ejections (CMEs), and other violent events on the surface can be measured by SOHO and serve as a warning that disturbances in the solar wind may reach the Earth within a matter of days.
