Dark Sky Alqueva Reserve

Alqueva is the first site in the world to receive the “Starlight Tourism Destination” certification. This certification, awarded by the Starlight Foundation is supported by UNESCO, UNWTO and IAC. Starlight destinations are visitable places characterized by excellent quality for the contemplation of starry skies, and the practice of tourist activities based on this resource.

The region of the Great Lake Alqueva in Alentejo, Portugal is a wonderful place to see the stars, constellations and distant galaxies such as the Milky Way. The unique characteristics of the night sky with a very low rate of light pollution, in the municipalities of Alandroal, Reguengos, Monsaraz, Mourão, Barrancos, Portel and Moura ensure the ideal conditions for an excellent observation of the dark sky. In Alqueva the sky has good atmospheric conditions for stargazing most of the year. Such skies are disappearing in Europe, where most of the population has no longer the privilege to observe an unpolluted sky.


Located at an altitude of 1000 m in the heights of Saint-Louis, the Astronomical Observatory of the Plaine des Makes will make you discover in a pleasant setting, what astronomy is.

The idea of an Observatory at Les Makes dates back to 1986, when Halley's comet passed. The village of Les Makes had a number of characteristics: discreet public lighting, clear sky and clear at night, reduced atmospheric turbulence, possibilities of accommodation in the village.

Thanks to these assets, the Astronomical Association of Réunion (A.A.R.), also founded in 1986, was able to obtain the collaboration of the municipality of Saint-Louis. The latter found great interest in developing this part of the Hauts de la commune. Work on the Observatory began on October 13, 1990 and was completed on September 20, 1991. The inauguration took place the next day in the presence of the very media HUBERT REEVES.

From the following year, an extension was necessary, including among others two work rooms. The inauguration took place on May 23, 1998 in the presence of the famous André BRAHIC, French specialist in planets, and Isabelle GRENIER, astrophysicist in Saclay. The Makes Observatory is managed by the A.G.O.R.A (Management Association of the Reunion Astronomical Observatory).

Nestled between the Nephin Mountains and the sublime unspoiled Atlantic coast, the Mayo Reserve Black Sky Reserve covers 150 km2 and allows you to admire the miracles of the night sky. The geographical location of the reserve gives it natural protection against pollution. On a clear night, it is possible to see, with the naked eye, more than 4,500 twinkling stars, to admire other planets of our solar system, to marvel at the Milky Way and the showers of meteors.

In an exciting collaboration between Cork City Council, the Cork Institute of Technology and a private benefactor, Blackrock Castle was re opened to the public in November 2007 as CIT Blackrock Castle Observatory, the Space for Science.

Their mission is to promote science, engineering and technology in Ireland as a centre of excellence in scientific research, education and outreach.

YellowKorner was created in 2006 by two friends, Alexandre de Metz and Paul-Antoine Briat, passionate about photography since their childhood. From this meeting arose an idea and an ambition: To make fine art photography accessible to all and to make YellowKorner the leading publisher of fine art photography.

The concept is therefore a very simple equation: instead of offering 10 prints at 5,000 euros, YellowKorner chooses to publish 1,000 to 50 euros while maintaining impeccable quality on the prints, the finishes and the choice of photographers.

At Paranal, ESO operates the Very Large Telescope, the world’s most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world’s largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is the European partner of a revolutionary astronomical telescope ALMA, the largest astronomical project in existence. ESO is currently planning the 39-metre European Extremely Large optical/near-infrared Telescope, the E-ELT, which will become “the world’s biggest eye on the sky”.
