18th November. Presentation on the etymology of common words and their relation with astronomy.
On Saturday December 2nd the planned activity is the construction of portable spectroscopes, where questions such as the nature and composition of light are explored, as well as the information that is possible to extract from the analysis of stellar light.
Saturday the 9th December, the planned activity is the construction of nocturlabes, 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 North Star.
The discovery of gravitational waves is one of the last pieces needed to confirm the Gravitation Theory of Einstein. The Professor Francisco Lobo, will bring us a short historical review of this remarkable discovery and discuss its importance and future usefulness.
Follow the usage of OLA’s main telescope and in the end, take the pictures with you. Learn more about Astronomy and Astrofotography, in this activity where our guests are the on-duty astronomers
On Saturday 16th of December, the planned activity is the simulation of how the craters on the planets are formed using spheres of different masses and diameters thrown onto various boxes with sand/flour to simulate the surface and composition of the planets.
