Historical Astronomers in Context – Homework #6

2. Nicholas Copernicus (1473-1543) was important to astronomy because he served as a pioneer in drifting away from the geocentric model of the universe. He dove tediously into the tables and mathematics of the previous, geocentric model of the universe and found enlightenment in geometry. He thereby successfully determined the distances between planets and the Sun, as […] Continue reading

Dark Matter

In honor of the pre-release of a song I wrote called “Dark Matter,” I wanted to do a post on the subject that inspired my song. The above picture is of the merging galaxy cluster Abell 520. This galaxy cluster formed from the collision of many massive galaxy clusters. The image shows dark matter, hot […] Continue reading

Historical Astronomers in Context

The astronomer I’ve picked is Sir Isaac Newton (Born January 4, 1643 – Died March 31, 1727).  Newton made discoveries that both directly indirectly impacted astronomy.  First, directly, Newton published the universal law of gravitation in The Mathematical Principles of Natural Philosophy, in 1687.  This law stated that the force of attraction between two objects […] Continue reading

Historical Astronomers in Context: Johannes Kepler

Who is Kepler Johannes Kepler’s most renowned contribution to astronomy was his development of the three laws of planetary motion. These three laws correctly defined the elliptic shape of all planetary orbits, established the equal area-equal time interval concept of solar radii, and equated the period of orbit with the size of the orbital elliptic […] Continue reading

“O, swear not by the moon…”

Johannes Kepler made important contributions to astronomy through his discovery that planetary orbits are ellipses. Kepler came to this conclusion after several years of painstaking effort trying to make sense of all the observations of his former master Brahe. Kepler also proposed three laws of planetary motion as a summary of his findings. Kepler was […] Continue reading

Copernicus in Context

Nicholas Copernicus: February 19, 1473 to May 24, 1543 Nicholas Copernicus was a pioneer in the astronomical community.

Historical Astronomers in Context: Tycho Brahe and the Age of Exploration

Tycho Brahe (1546 – 1601). Image source. Tycho Brahe was born 14 December 1546 in Knudstrup, Denmark. He was one of the most accurate astronomical observers before the telescope was invented, making extremely accurate naked eye observations. Though the consensus of the day was that the heavens were unchanging and any phenomenon that showed change occurred […] Continue reading
