   Explanation: After sunset on October 3, some of the Solar System's
   largest moons stood low along the western horizon with [6]the largest
   planet. Just after nightfall, a pairing of the Moon approaching first
   quarter phase and Jupiter was captured in this telephoto field of view.
   A blend of short and long exposures, it reveals [7]the familiar face of
   our fair planet's own large natural satellite in stark sunlight and
   [8]faint earthshine. At lower right are the ruling gas giant and its
   four Galilean moons. Left to right, the tiny pinpricks of light are
   Ganymede, [Jupiter], Io, Europa, and Callisto. Our own natural
   satellite appears to loom large because it's close, but Ganymede, Io,
   and Callisto are actually larger than Earth's Moon. [9]Water world
   Europa is only slightly smaller. Of the Solar System's six [10]largest
   planetary satellites, only Saturn's moon Titan, is missing from this
   scene. [11]But be sure to check for large moons [12]in your sky
   tonight.
