   Explanation: Saturn and Jupiter are getting closer. Every night that
   you go out and check for the next two months, [4]these two bright
   planets will be even closer together on the sky. Finally, in
   mid-December, a [5]Great Conjunction will occur -- when the two planets
   will appear only 0.1 [6]degrees apart -- just one fifth the [7]angular
   diameter of the [8]full Moon. And this isn't just any [9]Great
   Conjunction -- [10]Saturn (left) and [11]Jupiter (right) haven't been
   [12]this close since [13]1623, and won't be nearly this close again
   until 2080. This celestial event is quite easy to see -- already the
   two [14]planets are easily visible toward the southwest just after
   sunset -- and already they are remarkably close. Pictured, [15]the
   astrophotographer and partner eyed the planetary duo above the [16]Tre
   Cime di Lavaredo ([17]Three Peaks of [18]Lavaredo) in the [19]Italian
   [20]Alps about two weeks ago.
