It's been a little over a year since the first announcement
of a planet orbiting a star other than our sun. That first observation,
made by the Swiss team of Michel Mayor and Didier Queloz, was quickly confirmed
by Geoff Marcy and Paul Butler at San Francisco State University. About
one year ago I interviewed Geoff Marcy about his stunning observation. You
can hear this RealAudio interview
by clicking here.
Since then (actually since 1987...), Marcy and Butler have
been busy studying the spectra of 120 sun-like stars to see if they also
have planets. In the past year they have discovered six more planets!
This year I managed to catch not only Geoff, but also Didier
Queloz both in the same place for an Exploratorium exclusive, first-time
ever interview of the two astronomers who started it all! Click the

How do you look for planets you can't see?
To find a planet that even the most powerful telescope
can't see is quite a challenging task. Since we can't see the planet itself,
we look at something nearby that may be affected by the presence of a planet.
