Kepler-11 Planets

The Kepler space telescope has discovered a planetary system that is fascinating astronomers. Tourist’s Guide to the New Alien Planet System Kepler-11 – [space.com] The new discovery of six alien planets orbiting a sunlike star may be only a small part of the data released today (Feb. 2) from NASA’s planet-hunting Kepler mission, but it […]

1546 – Brahe – bio

Tycho Brahe was born in 1546 in Sweden. He was an astronomer and alchemist who is known for his contributions to astronomy. While he was probably the last astronomer to work mostly without a telescope, he revolutionized the use of precise instrumentation in astronomy. Because of this precision, he was able to discover and document […]

-0310 – Aristarchus – bio

Aristarchus was born on the island of Samos in Greece around -0310. He was a mathematician and philospher and probably the first on record to propose that the Earth circled around the Sun instead of the other way around. He wrote a work titled, “On the Sizes and Distances of the Sun and Moon” which […]

Kepler Space Telescope

The objective of the Kepler space telescope is to search for planetary systems outside of our solar system. It will be placed into a solar orbit that trails Earth, so it can scan distant light sources with no interference, but also easily relay data back to Earth for analysis.

Solar Sails

Solar sails were first proposed by Kepler almost four hundred years ago. The idea of a solar sail is use a large expanse of a thin, light film to “catch” the pressure of photons in light and use that pressure to accelerate a space craft in a desired direction. Progress at NASA: A Brief History […]

1401 – Nicholas of Cusa

Born in 1401 in Kues, Germany, Nicholas became known as Nicholas of Kues or Nicholas of Cusa (Latin version of Kues) and was a Cardinal in the Roman Catholic Church. Nicholas attended the University of Padua in Italy and received his doctorate degree in canon law there. In addition to being a religious scholar and […]

1571 – Kepler – bio

Born in 1571 in the Stuttgart region of Germany, Johannes Kepler was a mathematician and astronomer. Kepler became the first published defender of the heliocentric theory of Copernicus. He described planetary orbits as platonic solids and then realized that the orbits are eliptical. Kepler studied the golden ration and wrote this about it: “Geometry has […]

1642 – Newton – bio

Isaac Newton was born in 1643 in Linconshire, England. He made exceptional contributions to physics, mathematics and astronomy and was also accomplished in philosophy and theology. His laws of motion and gravity became landmarks for centuries. He and Leibniz independently developed calculus. He investigated the refraction of light and created the first working reflecting telescope. […]
