Extrasolar Planets

As 600 SnG champs cashed in their tickets earned throughout the month for 2009's final $50,000 Battle of the Planets Triple Shootout freeroll, we had some well-known players make their runs at the $12,000.00 first prize sitting at the end of these three SnGs. New minted Team PokerStars Online Pro Thomas "Boku87" Boekhoff's attempt to gain in his $5 into $100,000 bankroll challenge fell short while heads-up in the first round against VIP...

In the recent decades it could be argued that Astronomy has been more about "far" than "small". Nowadays though the field of extrasolar planets is exploding. The field started with Jupiter type gas giants with orbits of a few days (very close to their stars), but now planets further away as well a  

A clone of Earth, or even a rough approximation, has proved a difficult thing for scientists to find. The catalogue of planets orbiting other stars grew to more than 400 entries in October , but the goal that drives much of the research into extrasolar planets, or exoplanets, is the discovery of a habitable world, and that goal remains unmet. Some rough approximations, however, are starting to come into view. [More]  

In 2008 astronomers discovered surprising amounts of water molecules where planets were forming near young stars. But how, they wondered, could those molecules survive? They should have been destroyed by ultraviolet radiation. In theory, planetary dust could block out UV rays, but the dust was bound up in the creation of those young planets. So what's protecting the water? Now researchers at the University of Michigan believe they have the...  

Astronomers announced this week that they've discovered eleven new planets in our universe. International teams, working separately report they've discovered new planets in orbit around stars 61 Virginis (with three confirmed), HD 1461 (one confirmed and two more likely) and 23 Lib (four confirmed) and HD 134987 (one more likely.)  

Astronomers Wednesday reported the discovery of the first known "Super Earth" with an atmosphere, a water world orbiting a nearby red-dwarf star. The detection of the planet only a bit larger than Earth, reported in the journal Nature, raises hopes of upcoming star surveys spotting another planet like ours. "The discovery itself is very exciting," says team leader David Charbonneau of the Harvard-Smithsonian Center for Astrophysics in...  

Physics Today: Three papers indicate new candidates for rocky Earth-type planets around other star systems. David Charbonneau and colleagues published in Nature the clearest evidence yet for a Earth-type planet only 2.7 times larger than the Earth. Two nearby stars,...  

Astronomy is the science of the exotic, but the thing that astronomers most want to find is the familiar: another planet like Earth, a hospitable face in a hostile cosmos. The Kepler spacecraft, which was launched last March, is their best instrument yet for discovering Earth-like planets around sunlike stars, as opposed to the giant planets that have been planet finders’ main harvest so far. Many predict that 2010 will be the year of exo...  

Image 1: 61 Virginis is one of only a handful of truly Sun-like stars that can be seen with the naked eye. Astronomers have discovered three low-mass planets orbiting the star. The image above is from NASA's Sky ViewImage 2:  This image from a simulation of atmospheric flow shows temperature patterns on one of the newly discovered planets (61Virb), which is hot enough that it glows with its own thermal emission. A movie of the simulation is...  

An international team of planet hunters has found four new planets orbiting two nearby stars that are very similar to the Sun. These discoveries point the way to the detection of potentially habitable worlds within a few years. Link:  http://www.unsw.edu.au  

Like most astronomers, Jim Kaler first became interested in astronomy as a child looking up at the stars. He has been interested ever since. This interest inspired Kaler, professor of astronomy at the University of Illinois, and his presentation "Other Stars, Other Planets," which is at 7 p.

Retrograde or spin-orbit misaligned planets are important for understanding the diversity of planetary systems, and they provide important evidence for assessing current planetary migration models.
