Astronomers Spot Fourth Potential Habitable Planet
2012-02-03 09:41:48

An international team of astronomers have discovered a potentially habitable planet 22 light years away orbiting a nearby star, reports The Telegraph. Scientists, led by Carnegie´s Guillem Anglada-Escudé and Paul Butler, discovered the triple star system with a planet orbiting one of the stars, clearly within the habitable zone, where its neither too hot nor too cold, making it suitable for liquid water to be present on the surface. The host star has a different makeup...

Could A Two Sun System Support A Habitable Planet Or Moon?

A team of University of Texas at Arlington (UTA) astrophysicists are suggesting that a habitable Earth-like planet could exist in a distant solar system recently discovered by NASA´s Kepler Space Telescope. Kepler-16b, a cold, gaseous planet orbiting two stars -- similar to the fictional Tatooine of Star Wars -- in the Kepler-16 system, was discovered by Kepler back in September. Based on the discovery, the UTA team conclude that an Earth-like planet could exist in the system´s...

Astronomers Launch Online Database Of Habitable Planets
2011-12-06 05:02:07

Only 15 planets and 30 moons could potentially support alien life, according to a new online catalog of habitable planets launched by astronomers on Monday. The Habitable Exoplanets Catalog (HEC) website describes the project as "an online database for scientists, educators, and the general public focused on habitable exoplanets discoveries." "The catalog uses various habitability indices and classifications to identify, rank, and compare exoplanets, including their potential...

The database suggests over 15 exoplanets and 30 exomoons as potential habitable candidates Scientists are now starting to identify potential habitable exoplanets after nearly twenty years of the detection of the first planets around other stars. Over 700 exoplanets have been detected and confirmed with thousands more still waiting further confirmation by missions such as NASA Kepler. Most of these are gas giants, similar to Jupiter and Neptune, but orbiting very dangerously close to their...

First System For Assessing The Odds Of Alien Life Proposed

Methodology could be used to catalogue newly discovered exoplanets, exomoons Within the next few years, the number of planets discovered in orbits around distant stars will likely reach several thousand or more. But even as our list of these newly discovered "exoplanets" grows ever-longer, the search for life beyond our solar system will likely focus much more narrowly on the relatively few of these new worlds which exhibit the most Earth-like of conditions. For much of the scientific...

Planet hunters have found hundreds of planets outside the solar system in the last decade, though it is unclear whether even one might be habitable. But it could be that the best place to look for planets that can support life is around dim, dying stars called white dwarfs. In a new paper published online Tuesday in The Astrophysical Journal Letters, Eric Agol, a University of Washington associate professor of astronomy, suggests that potentially habitable planets orbiting white dwarfs could...

Researchers from the University of California (UC) Santa Cruz and the Carnegie Institution for Science have discovered a new, roughly Earth-sized planet that they believe could sustain life, representatives from both educational institutions announced on Wednesday. The investigative team discovered the new planet in a "habitable zone" (an area located at the right distance from a star in order to receive just enough stellar energy to maintain liquid water at or near the surface of the planet)...

Tight double-star systems might not be the best places for life to spring up, according to a new study using data from NASA's Spitzer Space Telescope. The infrared observatory spotted a surprisingly large amount of dust around three mature, close-orbiting star pairs. Where did the dust come from? Astronomers say it might be the aftermath of tremendous planetary collisions. "This is real-life science fiction," said Jeremy Drake of the Harvard-Smithsonian Center for Astrophysics, Cambridge,...

The alien life forms that we are searching for might not be "life forms" after all--they could well be sentient machines, according to a senior astronomer at the SETI Institute. In an article published online in the journal Acta Astronautica, SETI's Seth Shostak writes, "Our experiments to find extraterrestrial life are predicated on the assumption that it is most likely to be found on so-called 'habitable worlds.' These are planets and moons where surface liquid water exists, and atmospheres...

Weird orbits of neighbors can make 'habitable' planets not so habitable Astronomers hunting for planets orbiting nearby stars similar to the sun are looking for signs of rocky, Earth-like planets in a "habitable" zone, where conditions such as temperature and liquid water remain stable enough to support life. New findings from computer modeling indicate that some of those exoplanets might fluctuate between being habitable and being inhospitable to life because of the forces exerted by giant...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
