Análisis de la app Behind the Stars para 23 de diciembre

Come with us BEHIND THE STARS and you'll see how – on your own or in a group. Four astronomical instruments await you on this journey. They come from one of the oldest museums in the world: the Mathematisch-Physikalischer Salon in Dresden, Germany. You'll learn how to use these historical instruments (a nocturnal, a sundial, a celestial globe, and an astrolabe) and be able to apply them in the real sky — right now, wherever you are. You can make use of 20 guided units or set out on your own in the new Exploration Mode. While you're exploring, you'll also come to see how the movements of the heavens arise: of the Sun, the Moon, and the stars.
