Take a few minutes from your day today and watch this video published by NASA. Three years ago (Feb. 11, 2010), NASA launched the Solar Dynamics Observatory (SDO), which provides high-resolution data of the sun.
This video has taken several clips from the SDO, showcasing events such as solar flares, storms and eruptions. Depending on which wavelength the SDO is recording at, scientists get different color views and "can track how material on the sun moves." As NASA explains, "such movement, in turn, holds clues as to what causes these giant explosions, which, when Earth-directed, can disrupt technology in space.
Pretty amazing stuff, and much easier to look at than trying to look at the sun up in the sky on a sunny day.
