Here are some amazing high-resolution photos of the sun, taken 1-31-08. You can almost see the 3 dimensional shape of the sun in these photos.
I was lucky enough in high school to be able to view the sun with my naked eye using a home-made high power telescope and UV filter over a period of 3 months. Its amazing how much the surface of the sun changes day to day.
It kind of reminds me of something out of the movie Sunshine.
