The best way to learn about eclipses of the moon is to go outside and look at one. Plus, it’s a good excuse to stay up late at night! Mr. Eclipse is a website that will tell you when the next eclipse of the moon is where you live.
Eclipses of the moon happen pretty often. There’s usually more than one in a year that you can see from your own yard, though you may have to try several times before you get a night when it’s not too cloudy to see the eclipse.
Just go outside (put a jacket on! it can be cold at night) about ten minutes before the eclipse and look up at the sky. A pair of binoculars is nice but you can see an eclipse of the moon just fine, even in a city, with just your eyes. It’s perfectly safe to look at the moon during an eclipse, just like any other time. You don’t need special glasses. The eclipse will last a little over an hour.
One cool thing about an eclipse of the moon is that you can see for yourself that the Earth is round like a ball. As the eclipse gets going, you can see that the shadow of the Earth on the moon is curved – that’s because the Earth itself is curved.
