Tonight's eclipse begins at around 2:00 a.m. EDT and will be from both North and South America.
"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 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."
Tonight, there is also a chance to see Mars up close when it passes within 57 million miles of Earth, its closest approach in six years.
WHO WILL BE WATCHING?!
