Copernicus however, had no physical evidence, but due to my adaption of the spyglass into a telescope, I am able to study Venus and provide this information. Galileo's Observations Galileo decided to demonstrate the great number of stars that actually existed by depicting a few star systems that were known to all and including the additional stars that he had observed.
He found that the terminator, the line separating the dark from the light, was not smooth but jagged, and that some areas were smooth and others rough. This nebula is conspiciously absent from Galileo's drawing of Orion.
The Hague was the scene of peace negotiations between Spain and the Netherlands, and the news of this device spread rapidly through diplomatic channels: a printed newsletter describing events in The Hague reached Venice in November, and hence came to Galileo.
The Milky Way then was just the view of these far distant stars from earth. But the intellectual earthquake he had unleashed would determine the shape of our modern world.
It was not until after Christmas — January 7, — that Galileo managed to improve it sufficiently to allow him to see Jupiter as a round disc, like a little full moon.
Galileo was accurate in some of his assessments about what were then considered nebulae and about the Milky Way. After learning of the newly invented "spyglass," a device that made far objects appear closer, Galileo soon figured out how it worked and built his own, improved version. When Galileo pointed his telescope at Jupiter, the largest planet in our solar system, he made a startling discovery.
Edward Stafford Carlos; translations with introduction and notes. This telescope then, should have be sufficient to view the Orion Nebula.
