Early this morning, the full Moon sat below bright Jupiter, nearly wiping out the planet in its glare. The image shows a greatly overexposed Moon and nearby Jupiter. (Light saturation and consequent spillage causes the Moon to appear much larger than it actually was.) Three of Jupiter's four Galilean moons can be glimpsed, two on the left of the planet and the third on the right. The order from left to right is Europa, Io, Jupiter, and Callisto. The fourth moon, Ganymede, is lost in the planet's glare and lies to Jupiter's immediate right.
