Reality is awesome!
A collection of photos from the space shuttle Discovery, trip up the east coast to the Smithsonian for permanent display.
On April 16, 2012 a minor flare on the Sun triggered a HUGE eruption of ionized gas off the surface. This prominence stretched for hundreds of thousands of kilometers, and NASA's Solar Dynamics Observatory got great shots of it! I collected a few into a video, and the detail is amazing and incredibly beautiful.
The Sun erupts!
