   Explanation: [5]Even though Jupiter was the only planet visible in the
   evening sky on February 2, it [6]shared the twilight above the western
   horizon with the Solar System's [7]brightest moons. In a single
   exposure made just after sunset, the Solar System's ruling gas giant is
   at the upper right in this telephoto field-of-view from Cancun, Mexico.
   The snapshot also captures our fair planet's own natural satellite in
   its young crescent phase. The Moon's disk looms large, its [8]familiar
   face illuminated mostly by [9]earthshine. But the four points of light
   lined-up with Jupiter are Jupiter's own large [10]Galilean moons. Top
   to bottom are Ganymede, [Jupiter], Io, Europa, and Callisto. Ganymede,
   Io, and Callisto are physically larger than Earth's Moon while
   [11]water world Europa is only slightly smaller.
