The Buenos Aires City Planetarium has a special Summer program: everyone’s invited to the telescope observations by night! The objective is to enjoy the sky and the stars as they shine in this side of the world, the southern hemisphere. Every Saturday and Sunday, from 8.30PM to 10PM (as long as it isn’t cloudy) you can have a wonderful glimpse of Buenos Aires sky.
The observations include: planet Jupiter, the Orion nebula, Sirius (the brightest star of the night), southern stellar cumulus and the moon (in the nights where you can see it at that particular time).
The Buenos Aires City Planetarium “Galileo Galilei” is located in Palermo neighborhood, in the corner of Sarmiento Avenue and Belisario Roldán Street, inside Palermo woods. From the distance you can see its 20 meters diameter top (full of shiny LED lights by night) which has become a symbol for local science since 1967 when it was opened. The building has five floors, six staircases and a room with 360 seats.
The planetarium (Zeiss Model M V) itself is located in the center of the main projection room and it has over 100 projectors and is approximately 5 metres (16 ft) in height and 2.5 tons in weight. It consists of a cylindrical framework with independent projectors for the Moon, the Sun and the visible planets (Mercury, Venus, Mars, Jupiter and Saturn) and two spheres in the extremes that project 8,900 stars, constellations and nebulas.
