Why Galileo Mattered

Posted on April 9, 2018 by Jeanie Zeng

When Galileo began using his invention, the telescope, for observation of the cosmos, he was very quickly able to make three discoveries. The most revolutionary of his discoveries were that the surface of the moon was rough and uneven and satellite objects he later identified to be moons orbited Jupiter. These discoveries were fundamental in challenging … Continue reading Why Galileo Mattered → Continue reading →

A Powerful Letter

Posted on February 12, 2018 by astronomydylan

Chapter 3 explained to us how Galileo solidified the Copernican revolution, and sealed the case on how Earth would be viewed in perspective of the universe. In 1615, Galileo wrote a letter to Grand Duchess Christina, in attempt to accommodate his observations’ confirmation of Copernicanism with the doctrines and scripture of the Church. He held … Continue reading A Powerful Letter → Continue reading →

The Earth’s Gravity

Posted on February 12, 2017 by jakesindelar

  Gravity on Earth acts on all objects with the same force. No matter their mass, objects fall and accelerate at a constant rate. Due to the air resistance of different shapes, this is not always apparent. On a planet or moon lacking oxygen, the law could be simpler to demonstrate. On Earth, falling objects…Read more The Earth’s Gravity Continue reading →

Most people credit Italian astronomer Galileo Galilei (1564-1642) with building the first telescope.  He did not, but he made great improvements and ingenious use of the instrument. Before the telescope were lenses.  In the 13th century, Italian artisans created lenses for glasses to be worn by scholars with failing eyesight.  The process of making glass was difficult, as unrefined … Continue reading Galileo’s Telescope Continue reading →

Historical Astronomers in Context

Posted on February 9, 2016 by philhawkins221

GALILEO 1564-1642 Galileo was extremely crucial to astronomy for many reasons. First of all, he was one of the first astronomers to fully utilize telescopes to observe the sky. As a result, his findings were based completely on his nightly observations – in a time where accepted published works were based largely on conjecture. Important […] Continue reading →
