First Habitable Earth Type Planet Found

  1. They say that water can exist there in liquid form, and where there is water, there can be life.

    But, the gravity is two times greater than ours so what must the inhabitants, if there are any, look like? The temperature is between 32 and 104 degrees Farenheit. It's just a mere 20.5 light years away.

    Woot!

    Exciting! Got to search for more information.

    Hal Clement wrote about possible sentient beings on a high gravity planet. I got to meet him in 1996.

    I'm glad I'm not the only one here who thinks this is really cool. As I logged online, the news item scrolled across the top of my screen -- and I immediately recognized it as one of those truly profound moments of life.

    It's not as profound as the moment at which we will find intelligent life ... but it is an important step along the way ... and maybe the biggest step we will take in my lifetime.

    Wow

    A friend of mine did a research project back in college on the effect of gravity on chicken egg development. He used a record player turntable to provide the g-force. It seems to me that development stopped well short of 2 g. Based on that, animal life may not be possible under those conditions.

    Oh, TOO cool!

    I'm betting that they would be squat and muscular, with very dense bones.

    I always like how on SciFi series all of the aliens are pretty much humanoid bipeds with faces.

    Suesquatch:
    I guess those movie & TV aliens look like that so human actors can play the part.
    I bet we've enjoyed some of the same books.

    First habitable Earth like planet outside Solar System discovered

    ...this planet takes only 13 days to complete one orbit round its star. It is also 14 times closer to its star than the Earth is from the Sun.

    However, since its host star, the red dwarf Gliese 581, is smaller and colder than the Sun - and thus less luminous - the planet lies in the habitable zone, the region around a star where water could be liquid!

    "We have estimated that the mean temperature of this super-Earth lies between 0 and 40 degrees Celsius, and water would thus be liquid," said Stiphane Udry from the Geneva Observatory, Switzerland and lead-author of the paper in the journal Astronomy and Astrophysics.

    "Moreover, its radius should be only 1.5 times the Earth's radius, and models predict that the planet should be either rocky - like our Earth - or covered with oceans," he said.

    "Liquid water is critical to life as we know it and because of its temperature and relative proximity, this planet will most probably be a very important target of the future space missions dedicated to the search for extra-terrestrial life. On the treasure map of the Universe, one would be tempted to mark this planet with an X," added Xavier Delfosse, a member of the team from Grenoble University, France....

    Fiction:
    Mesklin is a vast, inhospitable, disc-shaped planet, so cold that its oceans are liquid methane and its snows are frozen ammonia. It is a world spinning dizzyingly, a world where gravity can be a crushing 700 times greater than Earth's, a world too hostile for human explorers. But the planet holds secrets of inestimable value, and an unmanned probe that has crashed close to one of its poles must be recovered. Only the Mesklinites, the small creatures so bizarrely adapted to their harsh environment, can help. And so Barlennan, the resourceful and courageous captain of the Mesklinite ship Bree, sets out on an heroic and appalling journey into the terrible unknown. For him and his people, the prize to be gained is as great as that for mankind... Hal Clement's Mission of Gravity is universally regarded as one of the most important and best loved novels in the genre. The remarkable and sympathetic depiction of an alien species and the plausible and scientifically based realization of the strange world they inhabit make it a major landmark in the history of hard sf.

    Uh, no not ready to go. Wouldn't that just make me weigh more than here on earth?

    So thats why flying saucers are shaped that way. The aliens are probably 3 ft tall and 6 ft wide. I wonder if they look like a Violet Ompa Loompa. Geesh they must think us humans are pretty sick looking. Hey I'm finally skinny compared to this type of alien!
