Historical Astronomers in Context

Posted on February 4, 2024 by sabrinaalperin

Nicholas Copernicus was an essential figure to the astronomy world because he suggested the concept of the heliocentric model of the solar system. Unlike previous astronomers who believed that planets revolve around Earth, Copernicus postulated that the Sun is at the center of the Solar System and that all the planets, including Earth, revolved about […] Continue reading →

Johannes Kepler: December 27, 1571- November 15, 1630. Kepler was important to astronomy because he developed three laws of planetary motion. He determined that 1) planets orbit the sun on an ellipse, 2) in an orbit equal areas are swept out in equal times with planets moving faster the closer they get to a gravitational […] Continue reading →

Isaac Newton Isaac Newton’s major life work was his book Principia Mathematica where he detailed his three laws of motion, gravitational law and other astronomical phenomena. He also created Calculus independently of Leibniz. Using his law of gravity, he derived Kepler’s three laws of planetary motion.

Astronomical Discoveries in Context

Posted on February 3, 2024 by James Bamshad

Nicolas Copernicus was both a mathematician and an astronomer, born on February 19th 1473 and passed on May 24th, 1543. He studied astronomy and astrology at the University of Cracow, leaving before completing his degree. His most important work was establishing the heliocentric model of the solar system. He challenged the geocentric model that stated […] Continue reading →

Nicolaus Copernicus  —  Born February 19, 1473 | Died May 24, 1543 Copernicus was important to astronomy because he proposed the heliocentric system that explained how planets orbit around the Sun. His central idea was that Earth, in addition to orbiting the sun every year, rotates once daily on its own axis. The slow changes […] Continue reading →

The Universe Isn’t Kepler-centric!

Posted on February 2, 2024 by abbieychen

Johannes Kepler made three of the most influential discoveries to the field of astronomy, also known as Kepler’s Laws. Kepler was born on December 27, 1571 (a true Capricorn!), and died on November 15, 1630. In case you forgot: Kepler’s 1st Law: planet orbits are elliptical (not necessarily perfect circles!) and the Sun is at […] Continue reading →

Johannes Kepler (1571- 1630) Johannes Kepler was an important contributor to astronomy after he created the three laws of planetary motion. The first law states that planets move in elliptical orbits around the sun, and the second law states that planets move faster in their orbits when closer to the sun. Lastly, the third law […] Continue reading →

blog 2: Gravity over time

Posted on February 1, 2024 by matthewastro

Isaac Newton originally conceptualized gravity as a mutually attractive force between all objects with mass. Those who came before him, such as Galileo, had performed experiments and attempted to establish increasingly robust understandings of this force, but none quite unified the idea like Newton. The story goes that Newton saw an apple fall from a […] Continue reading →

Blog 1 – The Cosmic Calendar

Posted on February 1, 2024 by Leni Ertel

Cosmic Calendar Image The Cosmic Calendar summarizes the history of the universe into a way that is easy for humans to comprehend-one 12-month calendar year. The universe is about 14 billions years old, so each month of the year represents a little more than a billion years of the universe’s history. Using this model, all […] Continue reading →
