Manic Monday - Shine



Mo's word for today is SHINE.




Have any of you ever heard of EARTHSHINE?

When you think of Leonardo Da Vinci, you probably think of the Mona Lisa or 16th-century submarines or, maybe, a certain suspenseful novel. That's old school. From now on, think of the Moon.

Little-known to most, one of Leonardo's finest works is not a painting or an invention, but rather something from astronomy: He solved the ancient riddle of Earthshine.

You can see Earthshine whenever there's a crescent Moon on the horizon at sunset. Look between the horns of the crescent for a ghostly image of the full Moon. That's Earthshine.

Go over to Manic Monday for other participants.

I've seen Earthshine, but I never knew it was called that.

That video was fun, though!

I've always loved that image, but I didn't know what it was called. That's way cool!
