NASA’s Solar Dynamics Observatory (SDO) is capturing spectacular images of the sun in ten different wavelengths. NASA Goddard has produced this amazing HD video of the images. There is a lot going on:

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system.

I could just sit and watch this — it would make a fantastic screen saver.
