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.

I didn’t make the connection until I saw the scene from the movie!
A great movie, and Good Show to you, Gideon 7, for making it!

There were two things in this movie that were uncannily prescient. First, there was a poster for the Beijing Olympics in 2008 in the bedroom of Floyd’s son, and second, the plot revolved around the premise that the Americans didn’t have a craft available to go to Jupiter in time . That was similar to the situation between 2011 and 2020 when we had to rely on the Russians to get to the Space Station.
