The Solar and Heliospheric Observatory (SOHO)

The Solar and Heliospheric Observatory (SOHO) is a joint project by NASA and the European Space Agency that studies the Sun. Launched in 1995, it orbits the Earth-Sun L1 point, providing continuous, detailed observations of the Sun’s surface, atmosphere, and solar wind. SOHO helps scientists understand solar activity, such as solar flares and coronal mass ejections, which can impact satellite communications and power grids on Earth. Its data is essential for advancing knowledge about solar processes and predicting space weather, ultimately helping protect technology and infrastructure on our planet.
