Do you think there’s life on other planets? Is SETI a worthwhile activity? SETI , the Search for Extra-Terrestrial Intelligence, is the science of using radio telescopes to search the skies for signals from alien civilisations. This is a huge task. In our galaxy alone, there are an estimated 100 billion stars, and radio signals can be sent on millions of different frequencies. The first search was conducted in 1960, but no alien signals have been detected so far. You’re going to read part of an interview with a director of the SETI Institute in California, Dr Jill Tarter. How do you think she might answer these questions? 1 If you think you’ve detected an alien signal, what will you do? 2 Will you send a message in reply?
