Water vapour found on exoplanet


news.bbc.co.uk

Astronomers have found water vapour in the atmosphere of a giant planet outside our Solar System.

The detection in the extrasolar planet HD 189733b was made using Nasa's powerful Spitzer Space Telescope and is reported in the journal Nature.

The team looked for the signal of water absorption in starlight poking through the edges of the atmosphere when the planet passed in front of its star.

It is only the second time water has been detected on an exoplanet.

So..second time eh, I wonder how many more there are? Bet there's absolutely loads and the more they find, the more we learn.

Whether this will lead to any fantastic discoveries or revalations is yet to be seen. Nice find though.

You beat me to the post Nerbot. Nice find!

Scientists are always saying where there is water there is life. So I guess this can tell us that we are not alone. I'm not saying there is intelligent life on this planet but it sure shows the skeptics that alien life is out there and flying around in Space and our planet.

Wow! For water to be in the atmosphere, the planet must not be too
hot, or too cold (by human standards). At such a distance from Earth,
I wonder how they know that this "signal of water absorbtion" isn't
some other liquid vapor? If it is water, this is indeed a huge discovery.

But it's getting frustrating seeing so many news reports about
atmospheres and water on exoplanets, yet nothing that indicates
life actually exists on any of them. I wonder how scientists could
determine if non-intelligent animal life exists on an exoplanet?

When dealing with spectroscopy of distant planets, you have to understand that water merely means an H2O molecule. It doesnt matter if it's liquid, gas, or solid, it's all picked up the same way on spectroscopy from that distance.

Likely the planet has ice crystals in it's atmosphere, the mass of the planet is likely too low to force water to behave in the same fashion as it does here on earth.

Nevermind, I stand corrected.

I was right in thinking it was a gas giant... however, it is actually too hot for the water vapor to crystallize.

By exo-planet I thought they meant a planet outside of it's own solar system... they actually mean a planet outside of OUR solar system...

Go figure.

More guesses and specualtion, but hey why not...

Genesis Chapter 1.. God made and places all those planets and stars and sun where they are for US ON EARTH, for Times, Seasons and Signs.

If there is water there, GOD put it there to confound the fools..
