Sun Watcher

On February 11, 2015, NASA's Solar Dynamics Observatory, or SDO, spacecraft marked five years in space. Since its launch in 2010, SDO has provided incredibly detailed views of the sun 24 hours a day, capturing an image almost once every second. Through its constant surveillance, scientists have gotten an unprecedentedly clear picture of how massive explosions on the sun grow and erupt. Today, the spacecraft continues to send back tantalizing imagery that incites scientists' curiosity. By monitoring the sun in different wavelengths of light, researchers can observe how material courses through the sun’s atmosphere. Such observations hold clues to some of the sun’s deepest mysteries, like what causes solar eruptions, and why the sun's magnetic fields are constantly on the move. Watch the video to see highlights from the spacecraft’s past five years of sun watching.
