The Heliospheric Observatory, also known as SOHO, is a spacecraft launched by NASA and the European Space Agency in 1995. Its main mission is to study the Sun and its effects on the solar system. By observing solar activity, such as solar flares and coronal mass ejections, SOHO helps scientists understand how the Sun influences space weather and impacts Earth. SOHO is equipped with various instruments that capture images and data about the Sun's atmosphere and its magnetic field. This information is crucial for predicting space weather events that can affect satellites, power grids, and even astronauts in space. Through its continuous monitoring, SOHO has become an essential tool for solar research.
