In this video excerpt from NOVA: "Secrets of the Sun," learn about a NASA mission that provides high-quality, high-resolution images of the Sun. The Solar Dynamics Observatory (SDO), launched in 2010, is a sophisticated satellite that delivers nearly continuous high-resolution observations of the Sun. Researchers recall the excitement of seeing the first images from SDO and explain how data from the satellite will help advance solar science. High-resolution images from SDO show the Sun's surface and corona, including giant tornadoes, plasma bubbles, and two different views of a coronal mass ejection.
