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]An illustration showing the surface of a planet that has red lava
   flows and dark cliffs. A red star is seen in the background. Please see
               the explanation for more detailed information.

   Explanation: If you could stand on exoplanet LHS 475 b, what might you
   see? No one knows for sure but pictured here is an [3]interesting guess
   made by an Earth-based [4]artificial intelligence (AI) engine. The
   existence of the [5]exoplanet was indicated in data taken by the
   Earth-orbiting [6]TESS satellite but [7]confirmed and further
   investigated only this year by the [8]near-Earth Sun-orbiting James
   [9]Webb Space Telescope. What is known for sure is that [10]LHS 475
   [11]b has a mass very similar to [12]our Earth and closely orbits a
   [13]small red star about 40 light years away. The featured
   [14]AI-illustrated guess depicts a plausibly [15]rugged Earth-like
   landscape replete with [16]molten lava and with the central red star
   rising in the distance. Webb data does not as yet reveal, however,
   whether [17]LHS 475 b has an atmosphere. One of [18]Webb's science
   objectives is to follow up previous discoveries of distant
   [19]exoplanets to better discern their potential for [20]developing
   life.
