Well, I've heard the explanation for why the Moon looks reddish during a total lunar eclipse - but never quite this wonderfully, this graphically.
What makes the eclipsed Moon turn red? A quick trip to the Moon provides the answer: Imagine yourself standing on a dusty lunar plain looking up at the sky. Overhead hangs Earth, nightside down, completely hiding the sun behind it. The eclipse is underway.
You might expect Earth seen in this way to be utterly dark, but it's not. The rim of the planet looks like it is on fire.
As you scan your eye around Earth's circumference, you're seeing every sunrise and every sunset in the world, all of them, all at once.
This incredible light beams into the heart of Earth's shadow, filling it with a coppery glow and transforming the Moon into a great red orb.

There is a big event planned here in Recife, Brazil for the eclipse.

Wow. Just looked up Recife on Google. It's only about 8 degrees south of the equator. Are you able to see the Large and Small Magellanic Clouds or is it the wrong time of year, Brian? Or too much light pollution?
