   The featured image shows a night sky over a distant hill. The night sky
   has three bright objects: a crescent moon, the planet Venus (highest),
     and the planet Saturn. Taken together, the moon and planets make a
        happy face icon. Please see the explanation for more detailed
                                information.

   Explanation: Sometimes, the sky itself seems to smile. A few days ago,
   visible over much of the world, an unusual superposition of our Moon
   with the planets Venus and Saturn created just such an iconic facial
   expression. Specifically, a crescent Moon appeared to make a happy face
   on the night sky when paired with seemingly nearby planets. Pictured is
   the scene as it appeared over Zacatecas, México, with distinctive Bufa
   Hill in the foreground. On the far right and farthest in the distance
   is the planet Saturn. Significantly closer and visible to Saturn's
   upper left is Venus, the brightest planet on the sky. Just above the
   central horizon is Earth's Moon in a waning crescent phase. To create
   this gigantic icon, the crescent moon phase must be smiling in the
   correct direction.
