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

Unscramble the Blue Letters

You've heard about solar flares. We were very siseprrud to discover a super flare, a flare which is thousands of millions of tmies more powerful than those we see in the Sun. In one of the binary stras in our galaxy called FH Leo, we disrcevoed the super flare. And later we went to study the spectral stars to see is there anything strange with these objects. And we found that everything is normal. These stars are normal like the Sun. Age, everything was normal. So this is a mystery. It's one of the meyrtesis we still have, super flares. And there are six or seven similar cesas reported in the literature.

Original Text

You've heard about solar flares. We were very surprised to discover a super flare, a flare which is thousands of millions of times more powerful than those we see in the Sun. In one of the binary stars in our galaxy called FH Leo, we discovered the super flare. And later we went to study the spectral stars to see is there anything strange with these objects. And we found that everything is normal. These stars are normal like the Sun. Age, everything was normal. So this is a mystery. It's one of the mysteries we still have, super flares. And there are six or seven similar cases reported in the literature.
