It's Safe to Look at the Moon

From the article regarding the up-coming lunar eclipse: Unlike a solar eclipse, it is safe to look at a lunar eclipse – which is when the moon passes through the earth's shadow as cast by the sun. During the total phase, the moon appears to have a dark reddish

Funny Food
