Dicembre al Centro Astronomico di Arson

How are distances measured in astronomy? How do we know how far away planets, stars, and galaxies are? Throughout history, scientists have devised various methods, quite ingenious, to answer these questions. Discovering, to their surprise but also with great unease, that we live in a cosmos of ever-increasing dimensions, which have expanded at a colossal rate in recent decades.
The highlight of the telescope observation will be a surprising Moon, featuring a view, due to favorable libration, of the Sea of Crises, alongside the craters Cleomedes and Geminus. The sight of the craters Endymion, Langrenus, Vendelinus, Petavius, with its characteristic rift, and Furnerius will also be very spectacular. The planets Jupiter, Saturn, and Uranus will also be visible.
In case of bad weather, the telescope observation will be replaced by a projection at the planetarium of the starry sky of the season.
