Latest Johannes Kepler Stories
How do astronomers weigh a star that's trillions of miles away and way too big to fit on a bathroom scale? In most cases they can't, although they can get a best estimate using computer models of stellar structure.
NASA's Kepler mission Science Operations Center software system was named winner of the 2010 NASA Software of the Year Award by the NASA Software Advisory Panel.
In a bid to unlock long-standing mysteries of the sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star.
By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the Sun's solar cycle.
NASA reported on Thursday that its Kepler spacecraft discovered a planetary system with two planets crossing in front of the same star.
NASA will hold a media teleconference Thursday, Aug 26, at 1 pm EDT to discuss the Kepler spacecraft's latest discovery about an intriguing planetary system.
NASA's Kepler Mission has released 43 days of science data on more than 156,000 stars.
MOFFETT FIELD, Calif., June 15 /PRNewswire-USNewswire/ -- NASA's Kepler Mission has released 43 days of science data on more than 156,000 stars. These stars are being monitored for subtle brightness changes as part of an ongoing search for Earth-like planets outside of our solar system.
HAMPTON, Va., June 4 /PRNewswire-USNewswire/ -- A NASA scientist knows what he is looking for and what he may find under or in the Milky Way tonight. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) On Tuesday, June 8, at NASA's Langley Research Center in Hampton, space scientist William Borucki will present "Kepler Space Mission: Progress in the Detection of Earth-size Planets in the Habitable Zone of Solar-like Stars" at 2 p.m.
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...
