SDO News
The Solar Dynamics Observatory (SDO) is a mission by NASA launched in February 2010 as part of the Living With a Star (LWS) program. The objective of SDO is to observe the Sun and provide a deeper understanding of its behavior and its impact on Earth and near-Earth space. The observatory focuses on the study of the solar atmosphere on small scales of space and time and in many wavelengths simultaneously. SDO carries a suite of instruments that measure the magnetic field at the solar surface and provide a comprehensive view of the constant changes occurring on the Sun. These instruments include the Helioseismic and Magnetic Imager (HMI), the Atmospheric Imaging Assembly (AIA), and the Extreme Ultraviolet Variability Experiment (EVE). The data collected by SDO is vital for improving our ability to forecast space weather, which can have profound effects on Earth’s communications and power grids.
