There are four moons in this picture. One on the lower left, and three in the upper right.
Zooming in, we can see Jupiter and three of his moons.
And of course our moon.
Hundreds of years ago, sailors used charts of the moons of Jupiter to determine what time it is. By knowing the time, they could use star charts for navigation.
Had modern climate scientists been in charge of these charts, sailors probably would have sailed off into the abyss. Just like they are doing to government and civilization.
