Penn State Mysteries of one of the most fascinating nearby planetary systems now have been solved, report authors of a scientific paper to be published by the journal Monthly Notices of the Royal Astronomical Society in its early online edition on 22 April 2014. The study, which presents the first viable model for the planetary system orbiting one the first stars discovered to have planets -- the star named 55 Cancri -- was led by Penn State University graduate student Benjamin Nelson in...

Diamond Planet Not So Precious After All
2013-10-09 04:42:18

redOrbit Staff & Wire Reports - Your Universe Online What was believed to be the first planet discovered to be comprised largely of diamond most likely does not have a high content of the precious mineral after all, according to new research scheduled for publication in in the Astrophysical Journal. The planet, which is located approximately 40 light years from our solar system, was first analyzed in 2010. At the time, it was concluded that the world had a surface of graphite...

Lee Rannals for redOrbit.com - Your Universe Online One nearby super-Earth planet could have a lot more "bling" on it than our planet, because astronomers say it maybe a diamond planet. Yale University scientists reported in the Astrophysical Journal Letters that the surface of 55 Cancri e is likely covered in graphite and diamond, rather than water and granite. The planet has a radius twice of Earth's, and a mass eight times greater, allowing it to fall into the classification...

Image 1 - Light Of Alien 'Super-Earth' Detected By Spitzer

Lee Rannals for RedOrbit.com [ Watch the Video ] Light from a "super-Earth" planet that lies beyond our solar system has been detected for the first time by NASA's Spitzer Space Telescope. NASA said that although the planet, 55 Cancri e, is not habitable, meaning it is unable to support life, the detection is a monumental step towards searching for signs of life on other planets. "Spitzer has amazed us yet again," Bill Danchi, Spitzer program scientist at NASA Headquarters in...

Chemical clues on the formation of planetary systems The study of the photospheric stellar abundances of the planet-host stars is the key to understanding how protoplanets form, as well as which protoplanetary clouds evolve planets and which do not. These studies, which have important implications for models of giant planet formation and evolution, also help us to investigate the internal and atmospheric structure and composition of extrasolar planets.. Theoretical studies suggest that...

A group of astronomers recently spotted an exoplanetary eclipse of a star to reveal a "super-Earth." The planet, which lies 40 light years away, was named 55 Cancri e and is twice as big as Earth and nearly nine times more massive. Thi super-Earth planet is mostly composed of rocky material and supplemented with light elements like water and hydrogen gas.  Scientists estimate the planet's surface is much hotter than Earth, close to 4,892 degrees Fahrenheit. Josh Winn, the Class of...

An international team of astronomers have revealed details of a "super-exotic" exoplanet that would make the planet Pandora in the movie Avatar pale in comparison. The planet, named 55 Cancri e, is 60 percent larger in diameter than Earth but eight times as massive. Twice as dense as Earth "“ almost as dense as lead "“ it is the densest solid planet known, according to a team led by astronomers from the Massachusetts Institute of Technology (MIT), the University of British...

Astronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other. This surprising finding will impact theories of how multi-planet systems evolve, and it shows that some violent events can happen to disrupt planets' orbits after a planetary system forms, say researchers. "The findings mean that future studies of exoplanetary systems will be more complicated. Astronomers can no longer assume all planets...

A new way of reading light will sharpen the view of planets around other stars Thanks to the ability of astronomers to detect the presence of extrasolar planets orbiting distant stars, scientists today are able to examine hundreds of solar systems. Now researchers at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. have created an "astro-comb" to help astronomers detect lighter planets, more like Earth, around distant stars. The Harvard group will present their findings at...
