An Artful Observation of the Cosmos

Galileo and the Telescope

 

In the Starry Messenger (1610), Galileo published the first observations of the heavens made with the telescope. His report caused a sensation, as he claimed to discover mountains on the Moon, vast numbers of previously undetected stars and four satellites of Jupiter. The planet Jupiter moves through the heavens without leaving its satellites behind. The Earth and Moon both have mountains, seas, atmospheres, and both shine by reflected light. All of these discoveries might suggest that the Earth is also a wandering planet.

Galileo Telescope replica ( )

The optics, leather and gold tooling of the telescope suggest how scientific instruments were crafted with a combination of engineering expertise and bookbinding arts. Galileo’s telescope included two lenses, an ocular lens near the eye, and an objective lens at the far end of the tube.
