Your linked pic is one of the sun as seen through a Coronagraph.
The sun is constantly putting out huge quantities of energy which scales the electromagnetic spectrum, far less than 1% of 1% of 1% of which ever comes near the Earth. There is also a discharge of matter from the sun in the form of charged (magnetized) atomic particles.
This colorized picture is a mosaic of ultraviolet images from the orbiting TRACE satellite sensitive to light emitted by highly charged iron atoms. Growing in number, the intricate structures visible are the Sun's hot active regions with temperatures over a million degrees Fahrenheit and their associated magnetic loops.

The magnetic effect the sun has on the protons (atomic bits) it ejects is monumental, and they will upon occasion burst as they depart the Solar environment, resulting in a bubble effect, as seen in your picture.

- Look at this pic
- The down side of "bumping" feature...
- Sam, when will you learn these guys are all wanna be's. They know nothing. (n/t)
- Re: Magnetism -- not to be confused with gravity . . .
- Not too worry, Sam
- Moderator, Yeah YOU Robert
- It's a sun slowly going into supernova
- Now Sammy's playin his lill games over at BadAstronomy! (groan)
- Wow, look at that.
