Solar Dynamics Observatory

The Solar Dynamics Observatory (SDO) is a spacecraft that studies the Sun. It sends back pictures and data to scientists here on Earth. It allows scientists to study how the Sun changes over time and how it affects us here on Earth. SDO uses special instruments on the spacecraft to take pictures of the Sun and measure different types of energy coming from it. Scientists use the data SDO sends back to learn about the Sun and help make predictions about things like space weather.
