Here. They say that it's a 100% chance.

Of course, the planet being 20 light-years away, we're unlikely to meet those life-forms anytime remotely soon. Still, on a galactic scale, 20 light-years is pretty close. Perhaps life isn't too rare.

The picture makes the planet look like it has trees. Only right around the edges though.

"highest average temperature is about -12 degrees Celcius" / "one side is blazing hot and the other freezing cold" -> Be near the vertical equator or else

Would like to hear more on this when available.

I'm not feeling confident that they've found intelligent life, but I hope their results go with their claims that life is abound there! It'd be interesting to see just what's there for life.

Unfortunately, it'd be about a half of a lifetime to go there and back and report on it though. =/

I'd like to know what the atmosphere looks like on this planet.

If it is continuously heated from one side, and heat is continuously lost from the other, I don't think much life would exist outside the belt between the two zones where the temperature would be at a tolerable level. This planet is very different from the earth!

Actually, it'd take a lot longer. There and back takes light ~40 years, and our spaceships can't yet go even remotely that fast. Even if they could, relativistic effects would make it take a lot longer for us compared to for the ship.

I'm also a skeptic regarding the possible life on that planet. Part of why life works on Earth is because of the rotation and the moon. Sure it may meet the criteria for potential life but saying that 100 chance of life on that planet is kind of misleading. It makes it seem like they're sure there is life, instead of what they are actually saying which is that its 100% possible life could be on there due to its similarities to the Earth and its relationship with the sun.

While we don't have the ability to get our space craft up to the speed of light yet (or faster, for that matter), one thing they could do is install a communications array on this planet (or a nearby moon, if it's too hostile to set up a base camp) and send radio messages back to Earth. Radio waves travel at nearly the speed of light which would cut down on time needed for research data to return to Earth.

I don't see that happening within the next century though.

Well I was thinking that if we could go as fast as light someday. Kinda left that part out. Whoops.

Ah, if only space research was properly financed, then maybe that'd be possible.

We may not have the technology to reach it yet, or even the technology to properly see it yet, but now we have a target. Astronomy never fails to be interesting!



In case you're a fan of the artist's rendering of the planet, as seen in the article, NASA's Astronomy Picture of the Day has a high resolution version up for your viewing pleasure. It's 1600x1200!

Who else thought of Pandora when reading this? Maybe in 100 years we'll be sending cryogenic-ally suspended people there over a 6 year journey to mine some incredibly valuable mineral...

Or it could be the Mormon's Planet Kolob...

Actually, I recall hearing that other planets with intelligent life would be more likely to have stuff like octopi/giant squids and the like than something close to humans. I also recall hearing that had Earth not been hit by a planet way back when, Earth'd probably be far more marine-based, and we wouldn't have the moon.

This article probably could make more effort than it does to point out that that isn't a real photo and that while travelling at light speed would get you there in 20 years, our technology isn't nearly that fast.

Definitely a cool find... they just probably want to draw more attention to the real timescales involved. If we launched it today, in significantly more than 20 years, we could land a transmitter on this planet, and 20 years after its landing, we'd start receiving its broadcast. Barring some major breakthroughs in space travel and/or longevity, our generation probably won't see anything from this discovery.

Of course that just means we should all start researching faster (even FTL) travel, medical science so we can live long enough to see the results, and/or more powerful telescopes so we can at least see it from here.
