    Europa may just be a haven for life, and in our own solar system to boot. The possibility of life there is part of what inspired me to mention that moons have as much or more of a chance to harbor life than the planets they orbit.

    But intelligent life is a different story as the conditions that will bring forth intelligent creatures are much more restricted.

    I can agree with the Europa case but as I googled it I came to know that the surface temperature is ~50-125K which I think is too low for any life to exist! Though the concept of life in Europa's so called ocean is interesting. But we have to wait till 2020 to have the mission to launch. It will take some more years to get the data to support our concepts of life on Europa.

    The idea is, and there is evidence to support it, that even though the surface temperatures are well below the freezing point of water below the surface the tidal forces from Jupiter create friction which in turn warms an ocean below the surface and provides the conditions that could support life in the same way that life springs up on the floor of earths oceans where the crust is splitting apart and magma warms the water.

    I am getting the feeling of reading through the first chapters of Dan Brown's Deception Point.

    I wonder if this Dan Brown novel will cause as much ruckus as his last two (I doubt it).

    Interesting title.
    When I was 18, I spent a summer at the northernmost point in Québec called Deception Bay (57.3 degs North). Being 2.7 degrees south of the Arctic Circle, I almost experienced the "midnight sun".
    ("Only" 23 hours of sunlight!).
    An amazing experience.

    Exactly Bob!

    That's the very point that makes me think there may be a chance of life there.
    If (and I know its a big IF) there is something on Europa, no matter how primitive, then with life on two different bodies in our own tiny solar system, the conclusion must be that the cosmos must teem with it.

    Absolutely.
    Above the 60th parallel (the Arctic Circle) during the summer solstice, the sun is above the horizon all day. (This condition lasts for longer and longer the higher your latitude in summer, making the period of daylight last for weeks the closer you get to the Pole).

    Where I was, just South of the Antarctic Circle, the Sun rose (in the East at about 2 AM) to about 10 degrees altitude, and just went around the sky at that same height. It set just a few degrees West of where it rose 23 hours before, and rose back up an hour later. (It never actually got dark, the Sun spending an hour just a few degrees below the horizon, between 1 AM and 2 AM).

    During the winter, the sun is invisible above the Artcic circle for months at a time.

    Old Canadian joke: The Mountie (Royal Canadian Mounted Police) is conducting an investigation. He knocks on the igloo and asks the Inuit: "Tell me Sir, can you account fot your whereabouts on the night of December 25th to March 3rd?".

    These conditions are identical (but reversed) in the Southern hemisphere, and above the latitude of 60 degrees South (the Antarctic Circle).

    The only place on Earth where daylight and night time are an equal 12 hours each all year round is on the equator.
