FLOOR -1

How do we observe the Universe today?
What methods can we study the sky by?
How did astronomy become a science?

In 1609 Galileo Galilei, guide of this floor, pointed his telescope to the Moon and used for the first time an optical instrument to observe celestial objects at a high resolution. After the revolution brought by the Copernican model the Earth rotates round the Sun, not the opposite, and our astronomical knowledge has considerably improved thanks to the development of newer and better surveying instruments created for seeing not only the visible, but even the invisible: radio waves , microwaves, infrared, ultraviolet, X and Gamma rays.

Floor -1, where you can discover what the atmosphere is composed of, see infrared rays and sand a beam of light to the Moon, is thus devoted to showing visitors our ability of collecting and interpreting signals arriving from cosmos, both with instruments on the Earth and with probes and satellites sent to the outer space.
