We are not alone in the universe... and we are not who we think we are


A nice interview with Jill Tarter on the search for alien life. It is a fine interview. A nice moment is when she looks at how we ourselves are not of this world:
"We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star. We are the laws of chemistry and physics as they have played out here on Earth and we are now learning that planets are as common as stars. Most stars, as it turns out now, will have planets."
