- California & Carnegie Planet Search
Today, more than 100 planets are known outside our solar system. Now, a new adventure begins: The search for planetary systems that are more like our own.

- Hubble Spots an Icy World Far Beyond Pluto
NASA's Hubble Space Telescope has measured the largest object in the solar system ever seen since the discovery of Pluto 72 years ago. Approximately half the size of Pluto, the icy world is called "Quaoar" (pronounced kwa-whar).

- Other Planetary Systems?
Are there planets orbiting other stars beyond our solar system? We do not know for sure, but with the recent discoveries about 51 Pegasi, 70 Virginis and 47 Ursae Majoris the weight of evidence is now so strong that only a "devil's advocate" denies the conclusions.

- Planetary Detection Applet
This applet is a simulation of how extrasolar Jupiter like planets are discovered around nearby stars as a result of the Doppler 'Wobble' of the host star. Synthetic data over a given time frame with resolution of 25, 15 or 3 meters/sec can be chosen. Some of Marcy and Butler's real data is also available. Parameter tags control the number of measurements over a given time frame that are available for analysis. In this way, the applet also teaches students about sampling, signal-to-noise, and errors. A fitter that adjusts the mass of the planet and its orbital period (distance from the star) allows the student to determine the parameters for either the synthetic or real system. Try this one. You will like it.

- The Search for the Extrasolar Planets
This web page is an attempt to provide a review of humankind's quest for the discovery of planets outside our Solar System. In addition, a series of major web sites dealing with the search for extrasolar planets are listed.
