A core zone, devoid of any permanent lighting and witnessing an exceptional night quality.The IDSR includes 251 communes spread around the Pic du Midi de Bigorre and is distinguished in two zones: It covers 3,000 km 2, or 65% of the Hautes-PyrГ©nГ©es. Co-managed by the Syndicat mixte for the tourist promotion of the Pic du Midi, the PyrГ©nГ©es National Park and the Departmental Energy Union 65, its priority actions are the public education on the impacts and consequences of these pollutions as well as the establishment of responsible lighting in the Haut-Pyrenean territory. The IDSR aims to limit the exponential propagation of light pollution, in order to preserve the quality of the night. It's the sixth in the world, the first in Europe and the only one still today in France. Officially initiated in 2009, during the international year of astronomy, the Pic du Midi International Dark Sky Reserve (IDSR) was labeled in 2013 by the International Dark-Sky Association. The main-belt asteroid 20488 Pic-du-Midi, discovered at Pises Observatory in 1999, was named for the observatory and the mountain it is located on. Saturn's moon Helene (Saturn XII or Dione B), was discovered by French astronomers Pierre Laques and Jean Lecacheux in 1980 from ground-based observations at Pic du Midi, and named Helene in 1988. The observatory is located very close to the Greenwich meridian.

Since 1982 this T60 is dedicated to amateur astronomy and managed by a group of amateurs, called association T60. A 0.60-meter telescope (the Gentilly's T60 telescope) is also located at the top of Pic du Midi. The observatory also has a coronagraph, which is used to study the solar corona. ДЄ 2-meter telescope, known as the Bernard Lyot Telescope was placed at the observatory in 1980 on top of a 28-meter column built off to the side to avoid wind turbulence affecting the seeing of the other telescopes. This served as a basis for James Lovelock, a scientist working for the Jet Propulsion Laboratory in California, to predict that those planets had no life - a fact that would be proven and scientifically accepted years after. The results showed atmospheres in chemical equilibrium. In 1965 the astronomers Pierre and Janine Connes were able to formulate a detailed analysis of the composition of the atmospheres on Mars and Venus, based on the infrared spectra gathered from these planets. ДЄ 1.06-meter (42-inch) telescope was installed in 1963, funded by NASA and was used to take detailed photographs of the surface of the Moon in preparation for the Apollo missions. Gentilli funded a dome and a 0.60-meter telescope, and in 1958, a spectrograph was installed. It housed a powerful mechanical equatorial reflector which was used in 1909 to formally discredit the Martian canal theory. The 8 metre dome was completed in 1908, under the ambitious direction of Benjamin Baillaud. Д¬onstruction of the observatory began in 1878 under the auspices of the SociГ©tГ© Ramond, but by 1882 the society decided that the spiralling costs were beyond its relatively modest means, and yielded the observatory to the French state, which took it into its possession by a law of 7 August 1882. It is part of the Midi-Pyrenees Observatory ( French: Observatoire Midi-PyrГ©nГ©es OMP) which has additional research stations in the southwestern French towns of Tarbes, Lannemezan, and Auch, as well as many partnerships in South America, Africa, and Asia, due to the guardianship it receives from the French Research Institute for Development (IRD).

The Pic du Midi Observatory ( French: Observatoire du Pic du Midi) is an astronomical observatory located at 2877 meters on top of the Pic du Midi de Bigorre in the French Pyrenees.
