NASA has awarded five-year grants totaling almost $40 million to five research teams to study the origin, evolution, distribution, and future of life in the universe. The newly selected teams are from the University of Washington; Massachusetts Institute of Technology; University of Wisconsin, Madison; University of Illinois, Urbana-Champaign; and University of Southern California. Average funding to the teams is almost $8 million each. The interdisciplinary teams will become members of...

Is The Possibly Of New Life Forms Really So Alien?
2012-05-09 07:44:18

The idea of discovering a new form of life has not only excited astronomers and astrobiologists for decades, but also the wider public. The notion that we are the only example of a successful life form in the galaxy has, for many, seemed like an unlikely statistic, as we discover more and more habitable planetary bodies and hear yet more evidence of life's ability to survive in extreme conditions. A new essay, published May 8 in the online, open-access journal PLoS Biology, examines what...

NASA Announces 2012 Carl Sagan Fellows
2012-04-03 04:13:52

NASA has selected six planet hunters as the recipients of the 2012 Carl Sagan Exoplanet Postdoctoral Fellowships, named after the late astronomer. The fellowship was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars. The Sagan Fellowship's primary goal is to support outstanding recent postdoctoral scientists in conducting independent research related to the science goals of NASA's Exoplanet Exploration Program....

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...

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?
2012-01-11 09:44:13

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
2011-11-21 09:11:24

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...

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...
