Historical Astronomers in Context: Johannes Kepler
Johannes Kepler (December 27, 1571 – 15 November, 1630) was known for his incredibly influential three laws of planetary motion. When …

Historical Astronomers in Context
2) Johannes Kepler made a groundbreaking discovery when he determined planets’ orbits are ellipses, not perfect circles. This is important because it explained why previous models of our solar system were flawed. Additionally, Kepler’s laws give important information on how exactly orbits work. For example, his second law tells us that planets will cover area […]

Historical Astronomers in Context
Johannes Kepler (1571-1630) was important to astronomy because he was a master mathematician and calculator. He worked in conjunction with Tycho Brahe who, through his brilliant eyesight made a lot of readings. Kepler used these readings to make deductions of how the solar system and the universe work. His three laws still hold true today: […]

Johannes Kepler’s contribution to astronomy can be matched by few. The laws of planetary motion appropriately named Kepler’s laws are still used to this day for approximating planetary orbits. His equations and observations gave us insight into the relationship between orbital period and orbital distance. Ultimately, Kepler’s contributions to astronomy played a key role in […]

Historical Astronomers in Context – Kepler
Johannes Kepler’s(1571-1630) love for astronomy started at a young age. He had amazing mathematical prowess although challenged by poor vision which limited his ability in astronomical observation. During his prime years, he worked as an assistant to astronomer Tycho Brahe who collected numerous and accurate data of celestial positions in hope of building his own […]

In Conclusion…
As the semester comes to a close and my first semester taking an astronomy class ends on Monday, I can say that I was not expecting to learn half of the topics we read about. I’m just completed confounded by all the information that we learned about our Universe and our solar system. From […]

The Constant Search For Life
In this past week, three new planets have been discovered in Kepler’s habitable zone. These three planets are announced to potentially host life. This may or may not be true, but the thought of finding planets slightly larger than earth that are in the Goldilocks zone is exciting in itself. For me, this is what […]

Conservation of Angular Momentum and Kepler’s Second Law
Conservation laws are very important laws for celestial objects in the universe. Without conservation laws, all these celestial objects will not obey predictable motions as they do in this universe. I am going to talk about conservation of angular momentum in this post. Any objects orbiting or rotating have angular momentum. To change angular momentum […]

Historical Astronomers in Context
Johannes Kepler (December 27, 1571- November 15, 1630) Johannes Kepler was initially hired as Tycho Brahe’s apprenctice. When Tycho died, Kepler was left to make sense of his observations; after years of analyzing them and trying to make sense of them in terms of circular orbits, he finally realized that planetary orbits are ellipses, not circles. […]

Historical Astronomers in Context – Johannes Kepler
Johannes Kepler (1571-1630) was a 17th century astronomer born in the city of Weil der Stadt in the Holy Roman Empire, in what is today Germany. He is best known for his discovery of the elliptical orbits of planets and his planetary laws of motion. These three laws explained that the planets orbited the sun […]
