In the three years since NASA launched the Solar Dynamics Observatory (SDO), the spacecraft has provided continuous, high-resolution views of the Sun, helping us better understand our star and its influence on us. Among other accomplishments, SDO also has studied the atmosphere of Venus as the planet passed in front of the Sun, and it revealed how a comet’s tail was buffeted by the solar wind as the comet passed near the Sun.
