An update from Yale’s Debra Fischer about the Alpha Centauri planet hunt, partially sponsored by The Planetary Society, as well as her team’s efforts to remove “noise” from parent stars to help find exoplanets.
The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.
What have the recent discoveries of thousands of exoplanets told us about how we got here, and whether we are alone? In Destiny or Chance Revisited, Stuart Ross Taylor attempts to answer those two questions.

The Planetary Society sponsored Alpha Centauri planet search started using a newly upgraded system in May. Here is a quick update including info from project leader Debra Fischer from Yale about their new system.
I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!

First Planet Discovered in Alpha Centauri System
Information on the Discovery, and also Insights from Debra Fischer
European astronomers have made the first planetary discovery in the closest-to-Earth Alpha Centauri star system. Here is some information about the discovery, and insights from Yale Astronomer Debra Fischer, who leads another Alpha Centauri planet search partially supported by The Planetary Society.
Someone on Twitter pointed me to a paper recently posted to ArXiv titled "Evidence for 9 planets in the HD 10180 system." If the (tentative) conclusion holds up, HD 10180 will be the first exoplanetary system known to have more planets than our own.

A large team of researchers has announced in a Nature article the discovery of not one, but two, Earth-sized planets orbiting a star named Kepler-20. This article separates the observational facts from the quite-likely-to-be-true inferences from the downstream speculations.

Some parallels exist between Odysseus' journey and the discoveries of exoplanets. What initially started out as a well-planned trip from Troy back to Ithaca, turned into a series of rather unfortunate events, with episodes of fighting Cyclops and having your crew turned into swine.
