                        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.

   Explanation: Shrouded in a thick atmosphere, the surface of Saturn's
   largest moon, Titan, is really hard to see. Small particles suspended
   in Titan's upper atmosphere cause an almost impenetrable haze, strongly
   scattering light at visible wavelengths and hiding surface features
   from prying eyes. Still, Titan's surface is better imaged at infrared
   wavelengths, where scattering is weaker and atmospheric absorption is
   reduced. Arrayed around this visible light image (center) of Titan are
   some of the clearest global infrared views of the tantalizing moon so
   far. In false color, the six panels present a consistent processing of
   13 years of infrared image data from the Visual and Infrared Mapping
   Spectrometer (VIMS) on board the Cassini spacecraft orbiting Saturn
   from 2004 to 2017. They offer a stunning comparison with Cassini's
   visible light view. NASA's revolutionary rotorcraft mission to Titan's
   surface is due to launch no earlier than July, 2028.
