From the Ted Talk by Garik Israelian: How spectroscopy could reveal alien life

Unscramble the Blue Letters

The other day, my culalgeoe from Berkeley, Gibor Basri, emailed me a very interesting spectrum, asking me, "Can you have a look at this?" And I couldn't sleep, next two weeks, when I saw the huge amount of oxygen and other elements in the spectrum of the stars. I knew that there is nothing like that observed in the galaxy. It was ibdenlrcie. The only conclusion we could make from this is clear endievce that there was a supernova explosion in this system, which polluted the atmosphere of this star. And later a black hole was foermd in a barniy system, which is still there with a mass of about five solar masses. This was considered as first evidence that actually black holes come from spaevunroe explosions.

Original Text

The other day, my colleague from Berkeley, Gibor Basri, emailed me a very interesting spectrum, asking me, "Can you have a look at this?" And I couldn't sleep, next two weeks, when I saw the huge amount of oxygen and other elements in the spectrum of the stars. I knew that there is nothing like that observed in the galaxy. It was incredible. The only conclusion we could make from this is clear evidence that there was a supernova explosion in this system, which polluted the atmosphere of this star. And later a black hole was formed in a binary system, which is still there with a mass of about five solar masses. This was considered as first evidence that actually black holes come from supernovae explosions.
