  • NASA finds planet that’s just about right for life
     OP - December 06, 2011, 10:39 AM
    Quote
    Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the “habitable” zone and make for a surface temperature perhaps averaging a balmy 72 degrees.

    The planet, Kepler 22b, about 2.4 times wider than Earth, circles a star about 600 light-years from Earth, close by astronomical standards. The Kepler space-telescope discovery team announced the find at a briefing at NASA’s Ames Research Center in Moffett Field, Calif.

    “It is right smack in the middle of the habitable zone,” Kepler scientist Natalie Batalha said.

    I love stuff like this! Interesting how they need 3 transits (detected by miniscule dimming of the star) to confirm. I guess the first two set a potential orbital period (290 days in this case), and a 3rd transit after the same period confirms it is something orbiting the star. Apparently there are loads more where they are just awaiting a 3rd transit to confirm.

    Boy that is great news..  NASA is doing a great job.. Damn with out these religious rubbish sure there would have been many NASAs in different countries...

    But 600 light years distance... that is a looong distance., but what is with these silly names   Kepler-22b ., If they find hint of inhabitable planets they should give a better name..

    Yeah, I hope they find a nearer one. One light year is 10 trillion km. New Horizons (flying by pluto in July 2015) has escape velocity of 60,000 km/h or about 500,000,000 km per year. So it would take it 20,000 years to go one light year. To go 600 light years it would take it 12 million years to get to kepler-22b! I bet we could do considerably faster even today if we had to. Even 1 million years in hybernation / frozen embryos would be worth it if it buys life another billion years in a habitable zone.

    i don't think you can just plant human life on another planet. the fact that it's habitable doesn't mean it's adaptable for humans.

    Yeah they'd have to detect the atmosphere etc. in a lot more detail first. I think at most they'd send embryos so no-one's on a suicide trip.

    I'm just imagining but they would use advanced technology to freeze them and un-freeze them and  gestate the fetus, machines & videos/holograms to raise and teach the children. I guess very advanced robots would have to help with a lot of stuff including growing food etc.

    and where would they get food?

    life needs to evolve, unless you can artificially create everything from scratch and migrate all the ecologies with the flora, fauna, etc.
  • Re: NASA finds planet that’s just about right for life
     Reply #9 - December 06, 2011, 03:14 PM
    Same thing for food. I guess the robots would set up plants from frozen seeds in an eco system in stages, then grow the humans/animals in a predetermined order too. There would need to already be organic (not living) molecules on the planet (just as there is even in Titan's atmosphere) for the plants to grow from. They'd probably test and refine the ecosystem creation stuff on earth first in a simulated sterile setup.

    Another problem: its diameter is about 2.5 Earths, so the mass is about 6.5 times that of the Earth. Humans cannot stand on such a planet; the average person would weigh 500-600 kilos there! Roll Eyes

    kilograms is a unit of mass. mass doesn't change with gravitational attraction, weight does. the average person weighs~800N(this is a wild guesstimate, but i'd think the average person is ~80 kilos).

    ^mass doesn't change with gravitational attraction, but gravitational attraction is proportional to mass, so N on that planet is about 6.25x N on Earth.

    Alot of nonsense in some of the news, it will not take 600 light years to reach the planet if you were travailing at light speed. From the reference of the object traveling close to the speed of light it would get there in an instant, since time moves slowly the faster you travel. Yes, the plant would age by 600 light years and similarly this effect would be the same on earth, but you travailing at that speed would not age much. Its Time Dilatation.

    Carl Sagan explains it better then me:

    dude, the is right. a human would weight more on such a plant if the math is right.

    ftfy

    anyway, on to you worming your way out of this obvious scientific mishap:


    newtons != kilos. kilos are a measure of mass and newtons are a measure of weight. they are in no way interchangeable and that was the point i was making(your post was sort of smugly worded so i had to correct such a basic misunderstanding)

    also no shit gravitational attraction is proportional to mass, i didn't say it wasn't. it still makes the fact you used kilos as a measure of weight a basic mistake.

    yeah i understand his point but he said the average person would weigh 500-600 kilos. i'm calling out that mistake because it's sort of smug to jump on a thread like this(which is referring to a possibly mindblowing discovery) and say WELL SINCE ITS BIGGER WE'D WEIGH MORE THEREFORE WE CAN'T EVER LIVE THERE(which is probably wrong anyway) and make such a basic(like srsly, confusing units is a grade-school mistake) error is sort of ironic

    Well they would. What's wrong with his statement? Weight is commonly given in kilos, so it's reasonable as a means of comparison.

    Oh and incidentally, a Newton is a measure of force, if you are into being pedantic. Get it right. Tongue

    It would be very difficult for humans to live there with that much gravity. Not impossible, but certainly not any fun at all.

    However, if there is a similar temperature range to earth, and a similar atmosphere, there should be an extremely good chance of some life forms evolving there. That would be really interesting.

    weight is a force, and in this instance newtons are a measure of the weight(i do my research before jumping on a nigga for being smug).
