Explanation: What is that large dark spot on Jupiter? It's the shadow of Ganymede, Jupiter's largest moon. When Jupiter's moons cross between the Jovian giant and the Sun, they created shadows just like when the Earth's moon crosses between the Earth and the Sun. Also like on Earth, if you were in a dark shadow on Jupiter, you would see a moon completely eclipse the Sun. Unlike on Earth, moon shadows occur most days on Jupiter -- what's more unusual is that a spacecraft was close enough to record one with a high-resolution image. That spacecraft, Juno, was passing so close to Jupiter in late February that nearby clouds and the dark eclipse shadow appear relatively large. Juno has made many discoveries about our Solar System's largest planet, including, recently, rapidly expanding circular auroras.

Is there anyone dancing in that moon shadow?

[Lurker]

It’s a marvelous night for a moon dance.

What do you call the mouse shadow in the second moon?

When I read the title I thought it was referencing the Earth’s moon shadow on Jupiter and was highly skeptical LOL

CONGRATS! If you hadn't posted this from "2010: The Year We Make Contact", I would have. A very good movie that I enjoy rewatching, now however the conflict seems more real!

[Billthedrill]

Ahhh yes... the brightest reflection is off the lower right, and the size of jupiter compared to that size elongated shadow, casting on the surface wood mean that moon is about as big as saturn!!! how could anyone look at this pic and not raise a brow??
