Astronomy Picture of the Day

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

    [2]A strange orange landscape is shown. What appears to be light and
   dark orange rocks are strewn about. The landscape appears roughly flat
        all the way out to the orange sky and horizon. Please see the
                 explanation for more detailed information.

   Explanation: If you could stand on Titan -- what would you see? The
   [8]featured color view from [9]Titan gazes across an unfamiliar and
   distant landscape on [10]Saturn's largest moon. The scene was recorded
   by [11]ESA's [12]Huygens probe in 2005 after a 2.5-hour [13]descent
   through a [14]thick atmosphere of nitrogen laced with methane. Bathed
   in an eerie orange light at ground level, rocks strewn about the scene
   could well be composed of water and [15]hydrocarbons frozen solid at an
   inhospitable temperature of negative 179 degrees C. The large
   light-toned rock below and left of center is only about 15 centimeters
   across and lies 85 centimeters away. The [16]saucer-shaped spacecraft
   is believed to have penetrated about 15 centimeters into a place on
   [17]Titan's surface that had the consistency of [18]wet sand or clay.
   Huygen's batteries enabled the probe to take and transmit data for more
   than 90 minutes after landing. Titan's [19]bizarre chemical environment
   may bear similarities to planet Earth's before [20]life evolved.
