                        "description": "A unique NASA spacecraft launched February 11, 2010, called the Solar Dynamics Observatory, or SDO, has started delivering images of the sun that have astonished scientists. SDO is the most advanced spacecraft ever designed to study the sun and its dynamic behavior. The spacecraft can produce images with clarity ten times better than high definition television and provide more comprehensive science data faster than any solar observing spacecraft in history. The goal of the mission is to help scientists study solar activity to improve forecasts of how the sun affects Earth.On April 21, 2010, NASA held a live press conference at the Newseum in Washington D.C. to unveil the first images and videos from SDO—SDO's First Light.A version of the press conference with captioning is available. || ",
