Astronomer Garik Israelian (watch his TEDTalk) explained the secrets of spectrography yesterday. And last night, he answered a few of our followup questions by email — including some questions from TED’s Facebook fans: Tell me about your latest work with lithium and its significance for planet-bearing stars. Since year 2000, our group has been working […]
Astronomer Garik Israelian spoke at TEDGlobal on Wednesday, July 22, about spectroscopy — the art of examining the spectral signature of a distant object in the universe, and inferring its qualities and behaviors. When I asked him during rehearsal if he could stay for the whole conference, he said he had to leave early — […]
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.

Israelian explores distant objects in the universe using spectroscopy. By looking at the spectral signature of distant object, he can infer the qualities and behaviors of the objects. He thinks spectroscopy will be how we finally discover whether there is life elsewhere outside of our solar system. Israelian discovered that stars sometimes swallow their planets […]
