Alien Life: Will We Know It When We See It?

Full Program: 2014 World Science Festival | 01:33:30

Featuring Biochemist, Geneticist Jack W. Szostak, Physicist, Cosmologist, Astrobiologist Paul Davies, Planetary Scientist, Physicist Sara Seager, and Astronomer Dimitar Sasselov with Journalist John Hockenberry Moderating

What are scientists looking for when searching for alien life? A lot, it turns out: the search for extraterrestrials requires the help from astronomers, planetary scientists, chemists, computer scientists, and geneticists, just to name a few. But are we barking up the wrong carbon-based tree? Could alien life develop in ways we haven't dreamed of here on Earth? Hear Paul Davies, Sara Seager, Jack Szostak, and other experts give updates on the search for life outside our planet in "Alien Life: Will We Know It When We See It?" part of the Big Ideas series at the 2014 World Science Festival.

Happy Birthday Carl Sagan He looked up at the vastness of space And how all the stars interlace In a massive expanse By design or by chance And it put a big smile on his face Carl Sagan was born on this date Long ago in the Empire State At a time of depression And Nazi oppression Inspired by malice and hate As a child he was thoughtful and curious Checking out both both the valid and spurious While hoping to see What the future might be And whether or not it should worry us He went to museums a lot When his friends were all out smoking pot He asked questions galore Then came back and asked more With much wonder and joy he was fraught Carl taught at Cornell while he wrote More than 600 papers of note And best sellers as well Made his bank balance swell He could always be good for a quote He wrote Contact, which Hollywood took From a clever, provocative book To the silvery screen Rated PG Thirteen Moving faster than light was its hook With Cosmos he changed how mankind Observes how the stars are aligned And how much isn't known And what’s carved in to stone With the use of his wonderful mind Sagan died in his 63rd year On a day when we all shed a tear But his spirit remains In our souls and our brains As he travels his final frontier

So stop waiting for Superman and do something on your own, for starters join Greenpeace, then continue with Amazon Watch. Those were my first two, and I'm very glad I did. If everyone was a member of some conservation group, maybe things would actually get conserved.
