    Year Two: SDO Highlights On Its Anniversary

    News & Features

    In April of 2010, NASA's Solar Dynamics Observatory (SDO) released its first images, an event known for any telescope as "first light." Since then SDO has continually observed the ever-changing sun on quiet days and explosive ones: there have been more than 1000 solar outbursts since SDO sent back its first pictures of the sun, including flares, coronal mass ejections (CMEs), and the release of energetic particles that can be flung to the farthest reaches of the solar system. Here we describe some of the highlights of SDO science and observations during its second year.
