Gliese 667 is an awesome system. I chose 667Cc for a term paper in Astrobiology; it's one of the strongest candidates for life outside the solar system we yet know. smile

3 Habitable planets hmm I wonder what a sunrise would look like. Well time to add it to SpaceEngine.

HD 189733 b has been observed by Hubble to have a deep blue color; it is the first exoplanet to have its visible-light appearance determined in any way (as far as I know).

To change its appearance in SE, find the "HD 189733 b" entry in /catalogs/planets/ExoPlanets.sc and add the following to it:

Code
    Surface
   {
    colorSea        (0.40, 0.40, 1.00, 0.00)
    colorShelf      (0.40, 0.40, 1.00, 0.00)
    colorBeach      (0.40, 0.40, 1.00, 0.00)
    colorDesert     (0.40, 0.40, 1.00, 0.00)
    colorLowland    (0.40, 0.40, 1.00, 0.00)
    colorUpland     (0.40, 0.40, 1.00, 0.00)
    colorRock       (0.40, 0.40, 1.00, 0.00)
   }
     
   Atmosphere
   {
    Height  500
    Model  "Neptune"
    Bright  3.0
    Opacity  0.2
    SkyLight    5.0
   }

Changing the color parameters seems to prevent cloud generation, so it may not be necessary.

Ok I'll add one.

1000 confirmed exoplanets! Wohoo! biggrin

Two teams of scientists using the Wide Field Camera 3 aboard NASA’s Hubble Space Telescope have detected faint signatures of water in the atmospheres of five big exoplanets.

The five exoplanets, WASP-17b, HD 209458b, WASP-12b, WASP-19b and XO-1b, are hot Jupiters, massive worlds that orbit close to their host stars.

Discovered in August 2009, WASP-17b orbits a main sequence star about 1,000 light-years away in the constellation Scorpius. The planet has an especially puffed-up atmosphere.

HD 209458b orbits a Sun-like star in the constellation Pegasus, about 150 light-years away. This exoplanet has the strongest signals of water.

The signatures for the other three planets, WASP-12b, WASP-19b and XO-1b, also are consistent with water.

Dr Avi Mandell of NASA’s Goddard Space Flight Center in Greenbelt, who is the lead author of the paper describing the WASP-12b, WASP-17b and WASP-19b findings in the Astrophysical Journal (arXiv.org), said: “we’re very confident that we see a water signature for multiple planets. This work really opens the door for comparing how much water is present in atmospheres on different kinds of exoplanets, for example hotter versus cooler ones.”

Dr Mandell with colleagues explored the details of absorption of light through atmospheres the five exoplanets. They compared the shapes and intensities of the absorption profiles, and the consistency of the signatures gave them confidence they saw water.

“To actually detect the atmosphere of an exoplanet is extraordinarily difficult. But we were able to pull out a very clear signal, and it is water,” said Dr Drake Deming of the University of Maryland in College Park, who is the lead author of the study on HD209458b and XO-1b published in the Astrophysical Journal (arXiv.org).

The water signals were all less pronounced than expected, and the astronomers suspect this is because a layer of haze or dust blankets each of the five planets. This haze can reduce the intensity of all signals from the atmosphere in the same way fog can make colors in a photograph appear muted. At the same time, haze alters the profiles of water signals and other important molecules in a distinctive way.

I don't know if this fits here, but there is a possibility that NASA's Kepler Space Telescope has discovered exomoons. Exomoons that are the size between Mars and Earth.

That's quiote old, unfortunately Exomoons are very hard to spot, and I don't think we'll confirm any in near future, interesting article btw smile

I know it's an old article, but i didn't saw it located anywhere on the forum, and no news about exomoons either.
We will just wait and see if NASA will later in some years confirm the existence of exomoons.

Why NASA? Not only NASA explores the space. There are a lot of observatories and astronomical institutions across the world.

And 4 of them are Super-Earth planets located in the habitable zone biggrin

Here's the link so everyone can see it: http://www.nasa.gov/ames....Cvl5PNl
The discussion is still ongoing: http://www.ustream.tv/channel/nasa-arc?rmalang=en_US

EDIT: The live stream is over now.

EDIT: Now it's time soon to add these new planets into the planetary catalogue for Space Engine biggrin
I hope the new version 0.9.7.2 will come with it.

I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.
