Newly discovered planet "just right" for life

I would think that there would be little to no water on the 'hot' side of the planet. It would have evaporated and been carried toward the temperate zone by the warm winds long ago. It's possible that the moisture in the winds could have delivered most of the water to the cold side and would have left most of the water on the planet trapped in ice. Who knows how much free water there is in the temperate zone? There could be an abundance of it or there could be very little. It's impossible to say at this point. Again, that depends on the density of the atmosphere. Remember this fun guy from hig... [More]

Again, that depends on the density of the atmosphere. Remember this fun guy from high school physics or chemistry: Volume and pressure are inversely related (thanks to those no good Clapeyron, Boyle and Charles!). So increasing temperature would certainly increase volume, however if pressures were great enough, despite the heat, you could still have liquid water. Thanks for pointing that out Copa. I suppose with a deor of 'earth-like' it caused me to assume things that I shouldn't have (like atmosphere density). Consider it a not-so-small oversight on my part.

Thanks for pointing that out Copa. I suppose with a deor of 'earth-like' it caused me to assume things that I shouldn't have (like atmosphere density). Consider it a not-so-small oversight on my part. Aye. It's what? 1.5 times the size of our world? Most of everything is speculative, using gravity wobbles. In fact, I don't read anything about them actually seeing the planet on telescope, so. . . I'm wondering if they even know for certain that the planet itself exists, let alone anything else at all about it.

in related News: First life-friendly exoplanet may not exist Last month, a team of astronomers announced the discovery of the first alien world that could host life on its surface. Now a second team can find no evidence of the planet, casting doubt on its existence. The planet, dubbed Gliese 581 g, was found to orbit a dim, red dwarf star every 37 days, according to an analysis by Steven Vogt of the University of California, Santa Cruz, Paul Butler of the Carnegie Institution of Washington in DC, and their colleagues. Unlike the four previously known planets in the same system and hundreds of ... [More]

its all bogus..... http://www.space.com/scienceastronomy/doubt-cast-habitable-alien-planet-gliese-581g-101012.html Man, that is depressing. I'll admit I was pretty excited about it, but absolutely skeptical of the "100% chance for life" claim. I suppose at this point we wait for more research to be done before a definitive answer can be made. Right now it doesn't look good. Wasn't this find substantiated by other observatories before it was made public, as it should have been? Or is that where we're at now in the process? Hmm.

So first he claims that he is 100% certain that this planet has life... and then after someone independently investigates the data and doesn't back him up (about the planet even existing in the first place...) he states I feel confident that anyone independently analyzing this data set will come to the same conclusions. Hmmm... I can understand taking pride in your work. I even admire that. But this just defies logic, unfortunately, and therefore I can't say that I admire ... [More]

I'm wondering if they even know for certain that the planet itself exists, let alone anything else at all about it. Called it. He should never have said 100% certain about anything. And the media reported it BEFORE there was independent confirmation? Aye, what a mess our information network is in. Whatever happened to scientists remaining cold and objective? He should stand by his findings, but he s... [More]
