Extrasolar Planets - Discovering New Worlds
We live on a small planet revolving around a star similar in size, luminosity and location in the galaxy as countless others.
We now know that other stars have planets orbiting around them the same as our star. Could some of these extrasolar planets be habitable like Earth?
Astronomers design and use complex instruments to simultaneously observe thousands of stars. By precisely measuring the light from each one they occasionally detect periodic changes in brightness - evidence that a planet is passing in front of the star.
Some of these worlds may harbour intelligent life. The alien inhabitants may even be aware of our presence. Discover how we have unintentinally been transmitting signals towards them for a long time.
