Its mission is science, but since NASA's Solar Dynamics Observatory (SDO) was launched in 2010, it's been sending some just-plain stunning images of the sun back to Earth. The SDO spacecraft is the first mission launched for NASA's Living With a Star (LWS) Program, designed to understand the sun's influence on Earth.
