    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: On May 20, a nearly Full Moon and Jupiter shared this telephoto
field of view. Captured when a passing cloud bank dimmed the moonlight, the
single exposure reveals the familiar face of our fair planet's own large
natural satellite, along with bright Jupiter (lower right) and some of its
Galilean moons [5] . Lined up left to right the tiny pinpricks of light near
Jupiter are Ganymede [6] , Europa [7] , [Jupiter] and Callisto [8] . (That's
not just dust on your screen ...) Closer and brighter, our own natural
satellite appears to loom large. But Ganymede, and Callisto are physically
larger than Earth's Moon, while water world Europa [9]  is only slightly
smaller. In fact, of the Solar System's six largest planetary satellites [10]
, Saturn's moon Titan is missing from the scene and a fourth Galilean moon,
Io, is hidden by our ruling gas giant.
