Solar Dynamics Observatory News

The Solar Dynamics Observatory (SDO) is a NASA mission launched in February 2010 as part of the Living With a Star (LWS) program, which aims to understand the causes of solar variability and its impacts on Earth. The SDO is equipped with three advanced scientific instruments: the Helioseismic and Magnetic Imager (HMI), the Atmospheric Imaging Assembly (AIA), and the Extreme Ultraviolet Variability Experiment (EVE), which together provide comprehensive measurements of the sun’s interior, atmosphere, magnetic field, and energy output. Operating in a geosynchronous orbit around Earth, the SDO supplies high-resolution images of the Sun in multiple wavelengths, offering unprecedented insights into solar activities such as solar flares, coronal mass ejections, and their effects on space weather. This continuous stream of data plays a crucial role in improving our understanding of the relationship between the Sun and the Earth’s environment.
