  • New Planet: Another Earth discovered by scientists?
     OP - October 01, 2010, 12:07 AM
    COURTESY: NATIONAL SCIENCE FOUNDATION
    R. Paul Butler, Planet co-discoverer
    Steve Vogt, Planet co-discoverer

    Astronomers have announced they have discovered an earth like planet that could support the crucial conditions needed for life to exist. The new planet sits directly in the middle of what is referred to as the habitable or Goldilocks zone (Gliese 581 g), unlike any of the nearly 500 other planets astronomers have found outside Earth's solar system. It also is in Earth's galactic neighbourhood, suggesting that plenty of Earth-like planets circle other stars. Astronomers say the planet is neither too far from its star, not too close and could contain liquid water.

    The boiling point of water depends on the atmospheric pressure.  It's only 100c at sea level, if you go up mount everest you can't make a warm cup of tea by boiling water because it boils + evaporates before it gets warm.  So if there were a lot of atmospheric pressure you could raise the boiling point beyond 100c.

    But the temperature will still be 400C even if water does boil @ different temperatures.  RIBS point was that the temperature is 400C, and that is still not conducive to life 'as we know it' under any atmospheric condition.

    IsLame, I am not sure I understand what you are saying.  Atmospheric pressure affects the boiling temperature of water.  It's only 100c at sea level, at higher levels it is lower.

    I think this is because temperature is energy/volume.  At lower pressure the volume for the same mass of water is greater and so the same amount of energy required to break apart the H2O molecules is actually a lower temperature.  You can put the same amount of energy in and increase the boiling temperature by compressing the liquid and therefore decreasing its volume.

    That is unless I haven't understood a fucking word of my physics and chemistry books and need to start re-reading them from the beginning Smiley

    As for "life as we know it" I suspect he may have meant carbon based.

    So do you mean that 400 degrees on planet Gliese will feel like 25 degrees on earth?

    Cause here on earth I cook my pizza with the oven on 250 for 10 minutes!

    If you touch something the perceived temperature depends on how much energy travels into your body and how focused that energy is.  The smaller the area the hotter it will feel.  So 400c on Gliese will feel the same as 400c on Earth. 

    I wasn't remarking on the temperature, I was saying that water can be hotter than 100c and still not boil.

    Yes, it changes the temperature at which water begins to rapidly vapourise, but the temperature is always the same i.e. 400C on that planet will be 400C on earth.  Whether its bubbling or not makes no difference here, life as we know it will be killed instantly at this temperature, and its still 400C regardless of pressure.

    Water doesn't change in volume. Its volume is effectively constant (unless you want to be really pedantic) so the change in boiling point has nothing to do with volume.

    RIBS didnt mention anything about pressure, or whether water was boiling or not.  Just that the temperature could not sustain life the chemical reactions required for life, and you mentioned pressures might be different, almost as if to say that would affect the temperature?

    A thermometer reading of a liquid @50C would be the same wherever you measure it, even if it happens to boil at this temperature at a higher altitude.

    That says 400 Fahrenheit, which is not nearly as hot as 400 Celsius. Still pretty hot though.

    Now if they screwed up and the temperature was 400 Kelvin that would be really interesting.

    Ok, I did not hear the Fahrenheit bit, but as you said, it is still very hot for our kind (400 degree Fahrenheit = 204 degree Celsius). Maybe some strange bacteria? But, what I did not like is the "like earth bit". Earth is not 200 degrees C! Double the boiling point.

    When you heat water its volume increases, when you cool it then it decreases.  

    I remember reading that to increase temperature you can compress.  Maybe that was only for gasses because liquids are already so dense.

    PS: I do like being pedantic, so if you care to elaborate I shall enjoy it Smiley

    What is indisputable though is that the boiling point of water does vary based on atmospheric pressure, it's only 100c at the pressure experienced at sea level on Earth.  A higher pressure will result in the water remaining a liquid beyond 100c so it won't be steam.

    There are life forms on Earth that live at around 400c.

    Rising as high as 15 stories off the ocean floor at depths of 7,000 feet (2,100 meters), hydrothermal vents that spew acidic, mineral rich water are the places to be - if you can stand the heat. The water coming out of the vents can reach temperatures as high as 750°F (400°C), but that's just fine to undersea thermophiles.

    Mars is much colder than Earth. Temperatures at the Martian surface vary from as low as about -195 degrees F (-125 degrees C) near the poles during the winter to as much as 70 degrees F (20 degrees C) at midday near the equator. The average temperature on Mars is about -80 degrees F (-60 degrees C).
