The planetarium itself is an impressive building. It was built in the Modernist style, which is otherwise not found in the city. It made of a giant sphere, which is supported by three large, low arches. The building is impressively large, with five floors. The planetarium itself is in the center of the building, and has over 100 projectors, including ones for the Moon, the Sun, Mercury, Venus, Mars, Jupiter and Saturn.
There are many exhibitions and activities at the planetarium, including interactive and photographic exhibits. Many exhibits are geared towards children, but most are enjoyable for young and old alike. Theatrical shows are even produced, such as the classic El Principito (The Little Prince), acted out beneath the stars. In addition, some shows are specifically for adolescents and adults, such as Galileo, which covers the most relevant points of this incredible man for which the planetarium is named. All programs and events are in Spanish.
From the planetarium, one can see many parts of the southern sky, including the Southern Cross, Argentine Antarctica, and the South Pole. It is a wondrous sight, for both young and old, and can be quite educational, as well. Here, you can study the sun, and learn about comets and shooting stars. Observation sessions are free of charge, and are open to the general public. Some of the exhibitions and shows may charge admission, but each tends to be under $10 pesos.
The planetarium also offers a variety of other courses and educational opportunities, as well as various conferences. Many local schools take advantage of this great resource, as well.
The museum is home to a piece of lunar rock which was donated by former U.S. president Richard Nixon, as well as many fossils from Argentina’s Neuquén Province and a meteorite that was found in Chaco Province, among other interesting artifacts.
The planetarium is open for scheduled events only. Telescope observing sessions are held Thursday through Sunday at 8:30 pm, and sun sessions are from 4:00 pm to 16:00 pm on Sundays. It is located on the corner of Avenida Sarmiento and Avenida Belisario Roldán, in the Bosques of Palermo.
