But it turns out it's easier to see what sort of elements and molecules there are in the planet's atmosphere than to image the surface. This will almost certainly happen in the next 10-20 years for some Earth-like planets. | ||

There's no way to know for sure if it does have life or not but I don't see why gravity would be a big problem. There's complex life deep in the oceans under 100s of times the atmospheric pressure. And smaller animals have less problem with gravity because the strength of their support structure increases decreases slower than the their mass. Finally, the difference in gravity is probably not that big. It's around 1.5 times the Earth's gravity if it has the same composition as Earth (maybe slightly higher). | ||

The thing is - can it support human life? 3.6 times the earth size means 3.6 times the gravity.. wouldn't we have to be like super strong just to stand there? (this isn't dbz) where we all train with super gravity on xD.. I'm curious to know how scientists would go about colonizing a planet that is like earth but with more gravity. It would take a long time to get there, what if you slowly turned the gravity up on yourself and could (if you had the ability to travel there I would assume you could). If it took many generations and you had someway to survive that might work. But I'm no scientist. | ||

So, while gravity does correlate to the size of the planet, it does so at a very small rate. For instance Jupiter is around 1300 times the size of Earth but it's gravitational field is only ~2.5 times stronger than Earth. In effect, yea there will be more gravity there, but not so much that it would feel abnormal too that large of an extent and human bones could easily support the added gravity. However, if it were a super large planet like Jupiter humans could always use some sort of metal support to move around I guess. | ||

It's great. now our parasitic race can take other planets and pollute the hell out of them after we overpopulate this one to the point of death =/ what a depressing thought Well, technically earth isn't overpopulated at all, just very mis-managed. There is more than enough viable land and food for every person alive on the earth, it's just that because of money, it's not available to people who are poor. That is one of the main reasons that we'll never go to another planet, we can't manage our own well enough to reap it's potential sustainable resources and be able to form a coordinated plan to go somewhere else. It is sad though, I agree. edit: thought I should source my statement source look at "carrying capacity" | ||

Let's say a ray of light leaves point A for point B, and point B is exactly one light year away when the ray of light leaves point A. Now, if the distance remains perfectly constant for one year, the light will reach point B after precisely one year. But what if point A and point B are moving away from one another? Then it would take longer than a year for the ray of light to reach point B, this is what is happening in our universe. Because light has a finite speed (it's bloody fast, but it's finite, it doesn't instantly move from one location to another regardless of distance), it is affected by changes in distance just like anything else. We can see this through redshifts. Thanks for clearing that up  | ||

![[image loading]](http://www.wired.com/images_blogs/wiredscience/2011/12/kepler22-b.jpg) For the first time, astronomers have found a planet smack in the middle of the habitable zone of its sunlike star, where temperatures are good for life. “If this planet has a surface, it would have a very nice temperature of some 70° Fahrenheit [21°C],” says William Borucki of NASA’s Ames Research Center here, who is the principal investigator of NASA’s Kepler space telescope. “[It's] another milestone on the journey of discovering Earth’s twin,” adds Ames director Simon “Pete” Worden. Unfortunately, the true nature of the planet, named Kepler-22b, remains unknown. It is 2.4 times the size of Earth, but its mass, and hence its composition, has not yet been determined. “There’s a good chance it could be rocky,” Borucki says, although he adds that the planet would probably contain huge amounts of compressed ice, too. It might even have a global ocean. “We have no planets like this in our own solar system.” Kepler-22b is 600 light-years away. Every 290 days, it orbits a star that is just a bit smaller and cooler than our own sun. The Kepler telescope, launched in 2009 to scan the skies for Earth-like worlds, found the planet because it sees the orbit edge on. That means that every 290 days, the world transits the surface of the star, blocking out a minute fraction of its light. Borucki likes to call the new discovery the Christmas planet. “It’s a great gift,” he said at a press conference here this morning. “We were very fortunate to find it.” The first of the three observed transits occurred only days after Kepler started observing. The third one was seen just before Christmas 2010, shortly before the spacecraft was unable to carry out any observations because of a technical glitch. Says Borucki: “We could’ve easily missed it altogether.” Source | ||

Well 600 light years might be far away for now ! I personnaly hope that, one day, we'll be able to travel that far. | ||

Cool series of pictures, but the artistic depictions of the large stars are not realistic. No way they have so well defined borders and are almost perfectly spherical, their atmospheres are very thin and their photospheres extended. off topic: The most realistic first contact scene ever shown in a Hollywood movie! | ||
