Kepler Supernova

The image above is of Kepler’s Supernova, which Johannes Kepler is credited with discovering with his description of the stellar object in his De Stella Nova. As stars progress through their main sequence lifetime and beyond and use up more of their hydrogen in nuclear fusion, they can fuse heavier and heavier elements. More massive […] Continue reading

Separation of Church and State (of Astronomy)

Johannes Kepler (1571 – 1630) was a massively important astronomer because he was the first to recognize that orbits were not perfect circles, but in fact ellipses. This was particularly significant because it allowed accurate predictions that supported the heliocentric model. He also found that orbiting objects move faster when closer to the object they […] Continue reading

Johannes Kepler in Context

Johannes Kepler was born December 27th 1571 and died November 15th 1630. Some of his most prolific discoveries lied in the three major laws of planetary motion. The first law concluded that planets move around the sun in an elliptical orbit. The second is that the time it takes for a planet to move around […] Continue reading

Johannes Kepler in Historical Context

Johannes Kepler (December 27, 1571 – November 15, 1630) revolutionized astronomy and improved upon the works of previous astronomers (including Copernicus and Tycho) in multiple ways. Kepler was able to develop a mathematical model of the universe that was heliocentric and was both more accurate and simpler than that of Ptolemy, whose geocentric model with […] Continue reading

Johannes Kepler: December 27, 1571 to November 15, 1630 (Image from Wikimedia Commons) Born in Germany during the 16th century, Kepler was born to a poor Lutheran family. However, his views on both a heliocentric solar system and his personal beliefs contradicting the Lutheran Faith in the Formula of Concord resulted in him alone in […] Continue reading

Johannes Kepler Kepler was born December 27, 1571, and died on November 15, 1630, at 58 years old. He was an astronomer, a mathematician, and a philosopher. He worked with Tycho Brahe and used his observations to deduce his first law of planetary motion: 1) planets move in elliptical orbits with the Sun at one […] Continue reading

2) Johannes Kepler (December 27, 1571—November 15, 1630) was incredibly important to astronomy and science as a whole because he bridged the gap between medieval and ancient “natural philosophy” to modern science. He was religious and, especially earlier in his life, placed a strong emphasis on integrating creation into his theories. This was common atContinue reading “Historical Astronomers in Context” Continue reading

Johannes Kepler (December 27th, 1571 – November 15, 1630) helped the world of astronomy and the general field of sciences in several key ways. First, Kepler utilized Tycho Brahe’s data concerning the position of stars and planets in the sky during different days in the year to determine that the orbit of Mars was elliptical […] Continue reading

Johannes Kepler: Context

Johannes Kepler was born December 27, 1571 and died November 15, 1630. Johannes Kepler, continuing Brahe’s work, discovered that planetary orbits are ellipses with varying levels of eccentricity instead of perfect circles. This helped him predict planetary positions and discover three laws of planetary motion. Kepler’s discoveries helped solidify the theory that planets move around […] Continue reading

Historical Astronomers in Context: Johannes Kepler

Johannes Kepler Born: December 27, 1571 Died: November 15, 1630 Important Contributions: Johannes Kepler and his discoveries were integral to understanding planetary motion in our solar system. Other than his three laws, Kepler was actually the first person to publish work defending Copernicus’ heliocentric model of the solar system. Copernicus did propose a heliocentric theory […] Continue reading
