How many hours have you spent looking at the sky without being able to find the Milky Way, the pole star or without knowing if that shinning bright spot is indeed a planet or not? To unravel the mysteries of the universe, the Centre of Astrophysics from the University of Porto organizes an open session every second Thursday of each month. The programme is divided into two stages. Firstly, there’s a simulation of the sky, where you can see all the stars and galaxies in plain sight. After the all the rightful explanations, demonstration is made outdoors, where you’ll be able to see the Saturn rings, the Andromeda nebula or the moon’s surface through a telescope.
