Here is a bit of NASA’s caption:
This “family portrait,” a composite of the Jovian system, includes the edge of Jupiter with its Great Red Spot, and Jupiter’s four largest moons, known as the Galilean satellites. From top to bottom, the moons shown are Io, Europa, Ganymede and Callisto. The Great Red Spot, a storm in Jupiter’s atmosphere, is at least 300 years old. Winds blow counterclockwise around the Great Red Spot at about 250 miles an hour. The storm is larger than one Earth diameter from north to south, and more than two Earth diameters from east to west. In this oblique view, the Great Red Spot appears longer in the north-south direction.
Europa, the smallest of the four moons, is about the size of Earth’s moon, while Ganymede is the largest moon in the solar system.
I like this picture because Liam did his science project on moons this year.
And while I am on the tangent of Liam and photos, might as well add Thomas. Dorothy (not Dorothea) has compiled some of Thomas’ photos. this is of us at his house, apparently in 1996.
