Lucianne Walkowicz: Let's not use Mars as a backup planet Stellar astronomer and TED Senior Fellow Lucianne Walkowicz works on NASA's Kepler mission, searching for places in the universe that could support life. So it's worth a listen when she asks us to think carefully about Mars. In this short talk, she suggests that we stop dreaming of Mars as a place that we'll eventually move to when we've messed up Earth, and to start thinking of planetary exploration and preservation of the Earth as two sides of the same goal. As she says, "The more you look for planets like Earth, the more you appreciate our own planet."

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 - Astronomy - Science - Space - Technology Related talks Discuss Enthusiastically agree? Respectfully beg to differ?
