First time in 456 years that a total lunar eclipse will happen on the first day of winter; and we're the lucky ones, living in Wyoming where you can see anything you want in the sky with practically no obstruction.

But NASA tells us 'don't blink, or we'll miss it.

For 72 minutes of eerie totality, an amber light will play across the snows of North America, throwing landscapes into an unusual state of ruddy shadow. The eclipse begins on Tuesday morning, Dec. 21st, at 1:33 am EST (Monday, Dec. 20th, at 10:33 pm PST).

An unusual natural wonder in the sky, and no telescope needed.

It Won't Look Exactly Like This.
