Mandatory PC Health Warning: Viewing the Sun with the naked eye may cause permanent eye damage and blindness. Observing the Sun through binoculars, telescopes etc. will burn a hole through your eyeball and out the back of your head before you can scream 'ARGHH! I'M BLIND!?', and may also cause permanent eye damage and blindness. Don't look at the Sun. Look at the Moon instead, it's much more interesting anyway.
