Astrobiology Top 10: Seeing a Distant Planet
Topic: New Planets
01/01/09
Summary: Astrobiology Magazine is looking back over 2008, highlighting the top 10 astrobiology stories of the year. At number 2 is the first visible-light photograph of an extrasolar planet. The planet is about the size of Jupiter, and scientists believe that the system in which it resides could harbor more worlds (This story originally was published on November 15, 2008).

The Evolution of EPOXI
Topic: New Planets
12/22/08
Summary: In this podcast, Tim Livengood and Vikki Meadows discuss the EPOXI mission and how it will be used to search for Earth-like planets in alien solar systems.

Some Planets are Better for Life
Topic: New Planets
12/18/08
Summary: A new idea proposes that worlds with the potential to host organisms can be split into four categories, each with their own likelihood of being inhabited. With extrasolar planet detection methods becoming ever-more advanced, these ideas could influence which worlds are studied first.

CO2 Found on Exoplanet
Topic: New Planets
12/13/08
Summary: The Hubble Space Telescope has identified carbon dioxide in the atmosphere of an extrasolar planet. The discovery is an important step toward identifying habitable planets beyond our solar system.

Solar System Snapshot
Topic: New Planets
11/16/08
Summary: Astronomers have captured the first infrared pictures of an entire solar system. So far, only three planets have been spotted - and they orbit a star that is only fifty percent larger than our sun.

Seeing a Distant Planet
Topic: New Planets
11/15/08
Summary: Astronomers have captured the first visible-light photograph of an extrasolar planet. The planet is about the size of Jupiter, and scientists believe that the system in which it resides could harbor more worlds.

Cutting Life Short
Topic: New Planets
10/23/08
Summary: Imagine a solar system where a life-bearing planet is slowly pulled in closer to its star. If life could survive the ensuing climate change, it would provide a clear example of the Gaia hypothesis in action.

Get Them While They're Hot
Topic: New Planets
10/22/08
Summary: Astronomers have determined that young, rocky planets stay hot longer than previously believed. The heat generated by these planets could make them easier to spot around distant stars.

Patterns in the Dust
Topic: New Planets
10/14/08
Summary: Astronomers may have discovered a new method for detecting planets as small as Mars orbiting distant stars. The method would open a new avenue in the search for habitable planets in the universe.

When Worlds Collide
Topic: New Planets
09/27/08
Summary: Astronomers have discovered that two terrestrial planets orbiting a distant star have recently suffered a violent collision. The new observation is unlike anything seen before, and sheds light on how interactions between planets can affect habitability.
