Additional Information


  • Samuel Pierpont Langley (August 22, 1834 – February 27, 1906) was an American astronomer, physicist, inventor of the bolometer and pioneer of aviation. Langley was the founder of the Smithsonian Astrophysical Observatory. In 1886, Langley received the Henry Draper Medal from the National Academy of Sciences for his contributions to solar physics. His publication in 1890 of infrared observations at the Allegheny Observatory in Pittsburgh together with Frank Washington Very was used by Svante Arrhenius to make the first calculations on the greenhouse effect.
  • The nomenclature of this region, which the LPL felt was vaguely identified in the IAU’s original Named Lunar Formations, was extensively modified, especially in connection with their Rectified Lunar Atlas (see Arthur’s report in IAU Transactions XIIB). Langley is apparently a new name added for a previously unnamed feature (in the IAU system), although Arthur says this is the same crater as the one labeled Regnault by Schmidt. - Jim Mosher
