Happening at OLA
 

Astronomical Observations

From Tuesday to Saturday at 21h30. During this two hour session, learn to find the polar star, identify the constellations and know their legends, relate stellar colours with their ages, observe star clusters, nebulas and faraway galaxies with the help of our telescopes.

Science Café: The beginning of the Universe

Oct 20th, 21h30. The cosmic background radiation allows us to look at the primordial moments of the creation of the Universe. In this presentation, Pedro Gil Ferreira describes the history of how we came to establish the current theory of cosmology where Einstein’s theory of Relativity and the extraordinary capacities of the recent astronomical observatories had a fundamental role.

 

Activities for Schools

Check here the available activities for schools, from the 1st grade up to the 12th grade.

Young Astronomers – Nocturnal

Saturday, October 13th, the planned activity is the construction of nocturnals, simple instruments that allow one to know the time by the observation of the Ursa Minoris Constellation (also known as Small Dipper, Small Bear, etc). There are also explored questions such as the Earth rotation, the origin of day and night and the orientation by the Northern Star.

Observation Platforms

The observation platform is located at the center of the observatory field. It is used as a support structure for large groups of astronomers and has a central role on the organization of star parties. It consists of a solid surface where tripods and pillars can be installed for telescopes and binoculars as well as other support equipment and with access to the electricity grid.

Auditorium

It is the main room where events such as talks, courses, workshops or even concerts happen. There are always two photography exhibitions displayed from either young or well known authors
