"I'm going to be the first human to land a spaceship on the Sun," a man boasts to his friends. "But you'll burn up!" they protested. "No I won't," he responded. "I'll make the voyage at night." Piloting a spaceship to the Sun would be a pretty dangerous enterprise.
Piloting a telescope to our nearest star isn't much safer. A sticker on most telescopes provides an ominous, helpful warning: "CAUTION! VIEWING THE SUN DIRECTLY WITH THIS TELESCOPE MAY CAUSE PERMANENT EYE DAMAGE!"
