Historical Astronomers in Context – Johannes Kepler

Posted on February 6, 2013 by rtjobe

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 […] Continue reading →

Moon Landing Evidence! :)

Posted on February 6, 2013 by drgrundstrom

In class today (Wednesday), I showed some of the lunar landing footage available to we, denizens of the Internet, for FREE!  NASA is a public entity and as such, happily will show us many awesome things and has given us the Apollo Lunar Surface Journal (ALSJ).  Much of the text was written by former astronauts […] Continue reading →

Tycho Brahe: Tycho’s primary contribution to astronomy is his collection of stellar and planetary observations. Accurate to within one arcminute, Tycho’s naked eye observations were unprecedented in quality. Tycho proved that comets lay in the realm of the heavens and sought to improve upon the current model of the solar system. Although Tycho never lived […] Continue reading →

Tycho Brahe: Historical Astronomers in Context

Posted on February 6, 2013 by zoodrey

sweet mustache! the 411 on Tycho Brahe: Brahe proposed a theory different than the one we support today (where the Moon orbits the Earth which orbits the Sun with the other planets) ; Brahe supported a geo-heliocentric solar system with the Moon and the Sun orbiting Earth and the remaining planets orbiting the Sun still. He … Continue reading » Continue reading →

Image Source Isaac Newton was very prominent and highly respected for his work in physics and mathematics. He was born the 4th of January 1643 and died the 31st of March 1727, and is important to Astronomy for several reasons: of those reasons, arguably the most relevant is his contributions to the science through his […] Continue reading →

Kepler and the elliptical orbits

Posted on February 6, 2013 by Elizabeth Merriman

Johannes Kepler produced remarkably accurate results from the movement of the planets.  After concluding that the planets move in elliptical orbits and that the planets sweep out equal area in equal time, he calculated the distance of the planets from … Continue reading → Continue reading →

Johannes Kepler in Context

Posted on February 6, 2013 by jacob933

Johannes Kepler (1571-16300) was absolutely vital to the study of astronomy in that he was the first to seriously propose that planets orbited the sun in ellipses, not circles. This greatly increased the accuracy of predicting astronomical events and helped to bring physics and astronomy a little bit closer together. Major Historical Events and People […] Continue reading →
