Latest Johannes Kepler Stories
Astronomers report that they have discovered two Earth-sized planets circling a dying star that has passed the red giant stage.
NASA announced on Tuesday that its Kepler mission has discovered the first Earth-size planets orbiting a star like our sun outside our solar system.
The Search for Extra Terrestrial intelligence (SETI) is back on track after funding from the U.S. Air Force Space Command.
NASA's Kepler mission has confirmed its first planet in the "habitable zone," the region where liquid water could exist on a planet’s surface.
A team of more than 65 astronomers, including those working at the National Optical Astronomy Observatory (NOAO) and NASA, discovered a new planet nearly the size of Earth.
NASA will host a news briefing at 8 a.m. PST, Monday, Dec. 5, to announce new discoveries by the Kepler mission. The briefing, during the Kepler Science Conference, will be in building 152 at NASA's Ames Research Center at Moffett Field, Calif.
Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
Kepler's Laws of Planetary Motion -- The astronomer Johannes Kepler's main contribution to astronomy was his three laws of planetary motion. Kepler found these laws empirically by studying extensive observations recorded by Tycho Brahe. He found the first two laws in 1609 and the third one in 1618. Isaac Newton was later able to derive the laws from his laws of motion and gravity, thereby producing strong evidence in favor of Newton's inverse-square gravitational law. Kepler's First...
Tycho Brahe -- Tycho Brahe (December 14, 1546 - October 24, 1601) was a Danish astronomer. He had Uraniborg built; which become an early "research institute". For purposes of publication, Tycho owned a printing press and paper mill. His best known assistant was Kepler. Tycho realized that progress in the science of astronomy could be achieved, not by occasional haphazard observations, but only by systematic and rigorous observation, night after night, and by using instruments of the...
