NASA's phenomenal Solar Dynamics Observatory has spent just over a year in space. During that time it has ceaselessly observed the Sun, returning incredibly detailed and exquisite images and videos. In high resolution we've seen sunspots, flares, coronal mass ejections, filaments, prominences, and towering loops of magnetic plasma. To celebrate, the folks at SDO put together this video featuring 12 of their favorite clips. I've written about several of these myself in the past year (see Related Posts below). Make sure you set the resolution to 720p!
