Stunning Pictures of a Solar Corona
Stunning pictures of a solar corona where temperatures around Sun reach

Shooting a million miles or more out into the hard, cold vacuum of space, this
fiery halo is one of the wonders of the universe.
Whipped into gigantic swirls by the Sun's ferocious magnetic fields, the shell
of super-hot gas is as beautiful as it is dangerous.
It's called a corona and can't normally be seen because of the brightness of the
Sun, a broiling sea of hydrogen gas at 10,000c. But during a solar eclipse, the
Moon blocks out the Sun and the corona is spectacularly revealed.
