Playlist (6 talks): Are we alone in the universe? 21:23Now playingThe SETI Institute's Jill Tarter makes her TED Prize wish: to accelerate our search for cosmic company. Using a growing array of radio telescopes, she and her team listen for patterns that may be a sign of intelligence elsewhere in the universe. 3:29Now playingCarolyn Porco shares exciting new findings from the Cassini spacecraft's recent sweep of one of Saturn's moons, Enceladus. Samples gathered from the moon's icy geysers hint that an ocean under its surface could harbor life. 18:29Now playingSo the Mars Rovers didn't scoop up any alien lifeforms. Scientist Penelope Boston thinks there's a good chance — a 25 to 50 percent chance, in fact — that life might exist on Mars, deep inside the planet's caves. She details how we should look and why. 19:11Now playingPhysicist Freeman Dyson suggests that we start looking for life on the moons of Jupiter and out past Neptune, in the Kuiper belt and the Oort cloud. He talks about what such life would be like — and how we might find it. 18:40Now playingSETI researcher Seth Shostak bets that we will find extraterrestrial life in the next twenty-four years, or he'll buy you a cup of coffee. At TEDxSanJoseCA, he explains why new technologies and the laws of probability make the breakthrough so likely — and forecasts how the discovery of civilizations far more advanced than ours might affect us here on Earth. (Filmed at TEDxSanJoseCA.) 6:38Now playingAstronomers believe that every star in the galaxy has a planet, one fifth of which might harbor life. Only we haven't seen any of them — yet. Jeremy Kasdin and his team are looking to change that with the design and engineering of an extraordinary piece of equipment: a flower petal-shaped "starshade" positioned 50,000 km from a telescope to enable imaging of planets about distant stars. It is, he says, the "coolest possible science."

Jeremy Kasdin: Zvjezdasta sjenica u obliku cvijeta koja bi nam mogla pomoći da nađemo planete slične Zemlji Astronomi vjeruju da svaka zvijezda u galaksiji ima planet, od kojih bi petina mogla biti nastanjena. Samo što nismo vidjeli nijedan — još. Jeremy Kasdin i njegov tim žele to promijeniti sa dizajnom i stvaranjem izvandrednog komada opreme: "zvjezdaste sjenice" koja dozvoljava teleskopu udaljenom 50000 kilometara da fotografira planete. To je, kako kaže, "najbolja moguća znanost." Similar topics - Planets - TED Conference - Astronomy - Space - Technology Related talks Discuss Enthusiastically agree? Respectfully beg to differ?
