Extra-Solar Planets

By Dr. Alex Filippenko







Summary:

Extra-Solar Planets Galore!

Because extra-solar planets are too dim to be seen directly, they are detected using a variety of ingenious techniques. Two examples: Minute variations in a star's spectrum and tiny changes in its brightness can signal the presence of planets.


Life Beyond the Earth

The recent discovery of extra-solar planets rekindles the age-old question of whether there is life beyond Earth. This lecture examines the possibility of rudimentary life on other planets and moons in the Solar System.
