biosphere foundation was founded inside biosphere 2 with the idea--if our coral is healthy, our biosphere is healththy, well, let's s go taka look at the health of our corals in biosphere 1. a ship p is the best t analogy a biosphere because you have aa crew, you have so many people that are on the ship. you have "x" amount of water, you only have so much food that you take with you, and you have to survive. bebecause you're not living b by yourself, you're living with 10 other people day in, day out, 24/7, you know? alling: we have inindonesians,se have singapore people, we have europeans, we have americans, plus all the local people from bali we work with. van thillo: we have whale recording system, all our dive setups to dive on coral reefs. studio of the sea is on mir, which is a traveling video studioio that makes educational film. and we can sail everywhere, so it's a perfect platform to study the ocean. dustan: corals, what we think of as stony corals that build reefs, are actually a symbiosis of the animal and a microalgae that lives in its tissues. the animal captures food from t

it's based on the experience of biosphere, biosphere 2 in arizona in the early 90s. you have really drawn a picture that is similar to, but, in so many ways, different from the real thing. - well, thank you. when the biosphere 2 experiment first happened in 91 through 93 northeast of tucson, i was fascinated by this. like most of the public, i clipped out all the articles. i thought, this is right up my alley because as you know, evan, i often write about ecological concerns. for those who don't know, a friendly texas billionaire-- - ed bass. - ed bass put up the money to create a new world. 3.15 acres, 3800 species of plants and insects, four men, four women, to be sealed inside for two years. this was the first closure of a projected 50 so this would go on for 100 years. the whole point is, nasa is still after this, by the way, is could we create another biosphere, other than the one we live in here, in the event that this one should collapse, which it sure looks like it's happening right now-- - honestly, it's about 50/50 isn't it? - exactly, or a mars colony, or

should we be faking this biosphere could extend out beyond one planet? >> that is a depression may have not thought that far but that we should take on the problem. but i will back up if you want to think about civilization they may be having a press conference they may appear to be in the inevitable so. that is of great question. >>. >> commandeers do you think it might take to have a handle of the atmosphere's of these exo-planets? >> so starting with hubble may concede the results. >> this is the first time they have appeared like this one is the closest runner-up >>. >> but i don't remember where. >> so back to social media. was sort of instrument could be used to answer the question? >> to go farther into the infrared spectrum to have a very powerful spectrograph it is the technique that we talked about them earlier to detect molecule's like oxygen so line of what sarah had suggested with the potential to harbor life. we really tried to emphasize the have the capability but nature has to deliver. but if nature has made life ubiquitous but with the a

should we thinking that the biosphere around this group of close net planets might extend past just one planet if they are close to each other? sara: that is a wonderful question, and we haven't thought that far yet. i'm sure there is a student out there listening who will take this problem on. i will answer a slightly different question, because if we want to think about intelligent civilization out there looking back at us, they may be having a press conference saying, there are three have a will place there, venus earth and mars, that appeared to be in the habitable zone. let's wait and see what out there. but great question, and hopefully somebody will work on this. felicia: next we have martha from the associated press. >> i was wondering, how many years do you think it might take to have a real good handle on the atmospheres of these exoplanets? we can make is substantial amount of progress in the next five years, starting with hubble and moving to continue the exploration of these atmospheres. we can see results in the early 20 20's. >> i know this is the first time some of these
