    Little do they know that once us humans step foot on that planet, we're going to find a flag planted into the ground that says "Chuck Norris Was Here." *shakes head*

    I like the fact they think it doesn't spin. I take it this means roughly one half of the planet is going to be frozen waste, if there's water that is.

    I wonder how many others there are out there.

    BTW, on a ever-so-slightly related astronomical note, has anyone seen just how big the star Antares is compared to our Sun? :eek:

    Well, I suppose it looks like we found a replacement for our planet once we finally kill it. ;)

    Actually, it is a cool discovery. Now we just need to figure out a way to get there. :)

    Hollow out Juno, set it spinning, name it Thistledown and send it off.

    Not to thread hijack, but here's a quick comparison off Wikipedia, showing our Sun, Arcturus and Antares to scale. That's one BIG ball of gas!!

    The black line BTW isn't the dimensions of Antares, but the orbit of Mars to the same scale. Antares stretches out to the edges of the yellow/orange circle. Sat at the centre of our Solar System, Antares would nearly reach the orbit of Jupiter.

    interesting. perhaps it has a very slow rotation though? suppose it'd take a while to figure out though.

    and that picture is astounding dynamicv.

    I wonder how far in comparison to our sun does a planet have to be to sustain life...

    I find it interesting, though, that Mars also satisfies the definition of an "earth-like planet" that is being applied to this planet. So it would not necessarily be suitable for human habitation...

    If it doesn't rotate isn't it unlikely to have a magnetic field strong enough to shield the planet from solar radiation?

    i think it's kind of neat, but it makes me wonder how long it would take us to get there. maybe we need to make some 'how to dvds', set up an invetro tube and launch a baby or 2 or more ;) and launch it towards that planet :)

    if we could only put half the effort into repairing this planet's problems, maybe we wouldn't need to worry about another one :)

    So is this a Class M planet? :D

    I read in our local papers that with our current-fastest spacecraft technology, it would take us 5 billion years to get there.

    We really need to work on lightspeed travel.

    That looks totally cool, and would lead to a great sequel: Dark Side of the 581 c
    Please send all flames to my private message inbox. Thanks!
    We really need to work on doing something other than launching missions to the ISS.

    i do too. but its probably due to the size, proximity to us, and other similar aspects. being in our solar system makes mars the most easily accessible planet for us to get to, and try to sustain life on at this point in time.

    The discovery of the new planet, named 581 c...

    Very sexy name there, although to be fair the fact that it's in the 'Goldilocks zone' does make up for it a bit.

    Nah, we're busy spending all our money killing ourselves. No time nore money to explore space. :p

    I would want to go and explore that planet. If that's ever possible.

    Holy mackerel, the math skills of your local papers are going down the toilet, not to mention knowledge of science. Maybe it would take that long if you walked. :rolleyes: The speed of light is "only" 186,000 miles per second or so. That comes out to more like 90,000 years (give or take a few thousand) at 150,000 mph, which you could probably achieve with a slingshot maneuver using traditional rockets. Plus we have ion drive technology now, which has ten times the thrust-per-pound of fuel compared to those traditional rockets. As long as you don't mind the leisurely pace of acceleration...how does 0 to 60 in 4 days sound. ;) But the thing with space is, there's no friction, so you can accelerate forever as long as you have enough fuel. Or until you reach the speed of light, which is the only speed limit that matters. :) So I'm sure we could shave off thousands of years from that time.

    Anyway, not anywhere near 5 billion years...what dingbat came up with that figure. But not quite an afternoon's drive, either....

    Found an even bigger star. It's toward the center of our galaxy.

    EDIT: Or this even bigger one. Link to full image.

    so... we found a planet that has a temperate climate and can sustain life. with that info, it stands to reason there is life there already (given the same building blocks for life is abundant).

    so, are we going to go there and war with them for the right to live there. i doubt they really want us any more than we would want an alien life to come take over our planet.

    we would have to kill all the intelligent life there to take over the planet. look what we did when we found the new world (americas). we killed 160m natives either through war or disease and relegated the rest to uninhabitable regions. we'll have to do the same thing there.

    why would they give up everything peacefully? we are not a peaceful race. we would not allow them to govern us. we feel we have a divine right to this universe. we are the best.

    we've just about killed our planet, and rather than fix it we would rather go find another one to conquer and devastate.

    WOULD YOU GO TO BE A SLAVE TO AN ALIEN RACE? of course not -- you would make them your slaves.

    we would pillage their planet of resources. think about what america currently does for oil. look what europe did to america for gold.

    we have a population explosion. the new planet probably does too -- or needs the room to expand on its own if it doesn't have that problem yet. why do we have the right to take someone else's home away from them. if there is a god, i don't think he'd very happy with our actions.

    LEAVE THEM BE! but that's not how it'll be -- there'll always be that little niggling in our minds now that we've found this new "EDEN".

    I admit that I did not really double-check their math. Granted, I also assumed speeds demonstrated by older spacecraft.

    Assume the distance from Earth to the outer planets is about 5 light-hours.

    It took our Voyager satellites some... 25-30 years to achieve this distance?

    This new planet is 20 light years away, or about 175,000 light-hours.

    OK, so that's about one million years. Phew. Perhaps there's hope for mankind after all ;)

    ... yes, you're right, there are probably ways to go much faster than Voyager satellites did.

    Now I'm starting to wonder just where my newspaper got its numbers.

    The odds are ok to find life on another planet, but to find intelligent life is another matter. By the time the human race actually gets to the point of exploring extra-solar worlds things will be much different. To live 581 c might require a change in the way we breathe air or a change in our physiology. They say 581 c has 1.6 times the gravity of the earth. So after a few generations of humans living there people may start to get shorter and have much denser muscles in order to adapt to the environment.
