An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed. Their work will be published by the Astrophysical Journal...

WASHINGTON, Aug. 16, 2011 /PRNewswire/ -- The month of August has 50 recognized holidays and national observances surrounding food, including National S'mores Day, National Lemonade Day and National Ice Cream Sandwich day. Despite all of the attention devoted to celebrating America's favorite foods, billions of pounds of food are wasted each year. Plastics Make it Possible®, an initiative sponsored by the plastics industries of the American Chemistry Council, partnered...

An international team of planet hunters has discovered as many as six low-mass planets around two nearby Sun-like stars, including two "super-Earths" with masses 5 and 7.5 times the mass of Earth. The researchers, led by Steven Vogt of the University of California, Santa Cruz, and Paul Butler of the Carnegie Institution of Washington, said the two "super-Earths" are the first ones found around Sun-like stars. "These detections indicate that low-mass planets are quite common around nearby...

Two nearby stars have been found to harbor "super-Earths""• rocky planets larger than the Earth but smaller than ice giants such as Uranus and Neptune. Unlike previously discovered stars with super-Earths, both of the stars are similar to the Sun, suggesting to scientists that low-mass planets may be common around nearby stars. "Over the last 12 years or so nearly 400 planets have been found, and the vast majority of them have been very large"•Jupiter mass or even larger," says...

Astrobiology Magazine -- In the land rush known as extrasolar planet hunting, the most prized real estate is advertised as "Earth-like." On Monday, June 13, scientists raced to plant their flag on a burning hunk of rock orbiting a red star. This newly discovered planet is about seven times the mass of Earth, and therefore the smallest extrasolar planet found to orbit a main sequence, or "dwarf" star (stars, like our sun, that burn hydrogen). There are even smaller planets known to exist...

Arlington, Va. - The world's preeminent planet hunters have discovered the most Earth-like extrasolar planet yet: a possibly rocky world about 7.5 times as massive as the Earth. This hot "super-Earth," just 15 light years away, travels in a nearly circular orbit only 2 million miles from its parent star, Gliese 876, and has a radius about twice that of Earth. All the nearly 150 extrasolar planets discovered to date that are orbiting normal stars have been larger than Uranus, an ice giant...

Arlington, Va. -- Taking a major step forward in the search for Earth-like planets beyond our own solar system, a team of astronomers has announced the discovery of the smallest extrasolar planet yet detected. About seven-and-a-half times as massive as Earth, with about twice the radius, it may be the first rocky planet ever found orbiting a normal star not much different from our Sun. All of the nearly 150 other extrasolar planets discovered to date around normal stars have been larger than...
