Spin it, zoom it, dive right into it. Using NASA's 3D Sun app, you can not only view features anywhere on the sun, but also interact with them. Here is a screenshot of today's big eastern coronal hole:
Cartoon spacecraft in the image mark the locations of NASA's twin STEREO probes. Stationed on nearly-opposite sides of the sun, STEREO-A and -B can see 98% of the stellar surface.
The two probes beam their green extreme ultraviolet images to Earth--and right into your iPhone or iPad.
The sun you spin is the realtime sun!
