Moons and Jupiter

From Fermilab Today Nov. 30, 2012: "The moon loomed large Wednesday night. This photo shows our moon, Jupiter and Jupiter's three moons as seen from the patio of the Users' Center. Click to enlarge and let it load— the photo is high-resolution. Zoom in on Jupiter (at roughly 11 o'clock relative to the moon) to see Jupiter's bands and its moons. Photo: Marty Murphy, AD"

Marty is a colleague and softball teammate. Actually, Jupiter has more than three moons, but only three are visible in this photograph.
