Tiny planets! http://www.nasa.gov/mission_pages/keple ... anets.html

Well, this proves that red dwarf stars can have very compact (Jupiter-scale) planetary systems...

And more planets orbiting close binaries!

Seriously, it's like the exoplanetary census is changing on a daily basis nowadays...

The AAS is setting up a website to collect all the Extrasolar planetary data (and exomoon data when it starts coming in). They are supposed to be including info on habitability. The article I read didn't have a link to that website though.. (Stupid Space.com)

Not sure if this is the one you were thinking of, but it's a damn good site!

http://phl.upr.edu/home (check out the LabNotes section in particular).

If you're on twitter you can follow the Prof who runs it at https://twitter.com/#!/ProfAbelMendez to get updates (https://twitter.com/#!/ExoClimes is also a good one to follow for exoplanet news).

I'm not sure if that is what the article was about either, but the Habitable Exoplanet Catalog seems to match.

Excellent site, thank you !

Gliese 667Cc looks like a very promising looking habitable world, and it's close to Sol too! (I just added it to the RECONS data on my Stellar mapping page the other day too!).

In a trinary star system no less. Amazing.

Let me see whether I have this right. Judging from the luminosity of Gliese 667 C and the orbital distance of Gl 667 Cc, Gl 667 Cc has a black-body temperature of 29 C, which is 12 K warmer than Earth's surface temperature. Is that right? Or is it that it would have a mean surface temperature of 29 C if its albedo and greenhouse effect had a combined effect similar to those of Earth?

Gl 667 Cc has a mass of about 5.2 M, which suggests a radius of about 1.73 times r, give or take for differences of gravity. That suggests a surface gravity about 1.73 g0, give or take for density. Escape velocity about 19.3 km/sec. Likely a dense atmosphere then: large greenhouse warming. It's going to be pretty warm down there on the surface.

Black Body temperature is without greenhouse effects. So, it is a bit warmer than Earth, but still within the liquid water range.

Depending on the atmospheric composition, it will likely be even warmer - Either tropical or desert depending on the amount of water.
