                        Astronomy Picture of the Day

    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.

   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
   featured color view from Titan gazes across an unfamiliar and distant
   landscape on Saturn's largest moon. The scene was recorded by ESA's
   Huygens probe in 2005 after a 2.5-hour descent through a 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 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 saucer-shaped spacecraft is believed to have
   penetrated about 15 centimeters into a place on Titan's surface that
   had the consistency of wet sand or clay. Huygen's batteries enabled the
   probe to take and transmit data for more than 90 minutes after landing.
   Titan's bizarre chemical environment may bear similarities to planet
   Earth's before life evolved.
