From: UFO UpDates - Toronto <post.nul> Date: Sun, 05 Feb 2012 18:46:53 -0500 Archived: Sun, 05 Feb 2012 18:46:53 -0500 Subject: New Super-Earth Detected Source: PhysOrg.Com http://tinyurl.com/87l9xyu February 2, 2012 New Super-Earth Detected Within The Habitable Zone Of A Nearby Star An international team of scientists has discovered a potentially habitable super-Earth orbiting a nearby star. With an orbital period of about 28 days and a minimum mass 4.5 times that of the Earth, the planet orbits within the star's "habitable zone", where temperatures are neither too hot nor too cold for liquid water to exist on the planet's surface. The researchers found evidence of at least one and possibly two or three additional planets orbiting the star, which is about 22 light-years from Earth. The team includes UC Santa Cruz astronomers Steven Vogt and Eugenio Rivera and was led by Guillem Anglada-Escud=E9 and Paul Butler of the Carnegie Institution for Science. Their work will be published by Astrophysical Journal Letters, and the manuscript will be posted online at: arxiv.org/archive/astro-ph The host star is a member of a triple-star system and has a different makeup than our Sun, with a much lower abundance of elements heavier than helium, such as iron, carbon, and silicon. This discovery indicates that potentially habitable planets can occur in a greater variety of environments than previously believed.
