Johannes Kepler: Historical Figures in Context

Who is he? Johannes Kepler (December 27, 1571 – November 15, 1630) was a revolutionary in many fields of scientific discoveries including optics and logarithms. He is important to astronomy most notably because of his work with planetary motion. As the first person to develop a set of physically and mathematically sound laws that correctly accounted for … Continue reading Johannes Kepler: Historical Figures in Context Continue reading Continue reading

Johannes Kepler December 27th, 1571 – November 15th, 1630 Image Source: High Altitude Observatory Kepler was a German astronomer and mathematician whose greatest contribution to the field of astronomy were his three planetary laws of motion. Using mathematical calculations, he discovered orbits are ellipses and that within such orbits, equal areas are swept out within […] Continue reading Continue reading

Johannes Kepler was born on Dec. 27, 1571 and died on May 21, 1630. He was important to astronomy because he made 3 key astronomical discoveries. First, and arguably most importantly, he discovered that planetary orbits are ellipses and not perfect circles as is it was popularly believed to be at the time. This was … Continue reading Historical Astronomers in Context Continue reading Continue reading

Historical Astronomers in Context

Johannes Kepler (December 27, 1571- November 15, 1630), summarized his discoveries with three physical principles. First, the planets move in elliptical orbits, but not perfect circles, with the Sun at one focus. Second, he argued that the time necessary to traverse any arc of a planetary orbit is proportional to the area of the sector between … Continue reading Historical Astronomers in Context Continue reading Continue reading

Historical Astronomers in Context

Johannes Kepler (1571-1630) was a German mathematician and astronomer who established the laws of planetary motion. He worked as Tycho Brahe’s apprentice. Although the two had a strained relationship, Kepler’s ability to find mathematical relationships among data proved the perfect complement to Brahe’s unparalleled observation skills. Through his work with Brahe’s observations, Kepler founded the … Continue reading Historical Astronomers in Context Continue reading Continue reading

Johannes Kepler was born on December 27, 1571. He died on November 15, 1630. Kepler came up with the Laws of Planetary Motion. His first law illustrates how the orbit of each planet is an ellipse, not a perfect circle. His second law states that the speed at which a planet moves is greater the closer … Continue reading Historical Astronomers in Context Continue reading Continue reading

Johannes Kepler: December 27, 1571 – November 15, 1630 Johannes Kepler made important contributions to astronomy, primarily from his studies of celestial mechanics. From his calculations and Tycho’s observations, Kepler developed his three Laws of Planetary Motion. First, “Planets move in ellipses with the Sun at one focus.” Second, “The radius vector describes equal areas … Continue reading Historical Astronomers in Context Continue reading Continue reading

Kepler in Context

Kepler, during his lifetime from December 27th, 1571- November 15th, 1630,  made incredible contributions to the field of astronomy. His most famous and impactful contributions are certainly his observations regarding the motion of planets, which have been immortalized as Kepler’s Laws. His discoveries about planetary motion stated that planets move in elliptical orbits, they sweep out […] Continue reading Continue reading

Living the fast life: Kepler-70b

The Kepler spacecraft (which was¬†feared lost earlier this week) has discovered a veritable treasure trove of exoplanets over its seven year mission. Some of these planets may even be habitable. Kepler-70b is decidedly¬†not one of them. Kepler-70b is the closer of two terrestrial planets to KOI-55, a subdwarf star which was once a red giant. […] Continue reading Continue reading
