How spectroscopy could reveal alien life: Garik Israelian on TED.com

Posted by: Emily McManus

Garik Israelian is a spectroscopist, studying the spectrum emitted by a star to figure out what it’s made of and how it might behave. It’s a rare and accessible look at this discipline, which may help us an Earthlike planet friendly to life. (Recorded at TEDGlobal, July 2009, Oxford, UK.Duration: 15:52)

    Very interesting. It’s amazing what science can do. Something to look forward to. The one thing I don’t like is how he assumes what can actually support life. What he should say is what can support life similar to ours as we know it. We have no other model of conditions that can support life. We assume that because our world has life that there can only be life where conditions are similar to ours. While that may be true, it may also be false. It simple terms, alien means different. So in my opinion different should include everything we can imagine and everything we can’t when referring to life beyond our world.
