Let's go hunting for planets on planetary radio.

Hi everyone, I'm Matt Kaplan. This time we visit with the most successful discoverer of worlds outside our own solar system.

We'll join Jeff Marcy of UC Berkeley as he works with our world's largest telescope.

Bruce Betts provides his regular update of what's up in the night sky,

along with the new trivia contest, and we'll get started with Emily Lachto-Wala's

Q&A about the first tourist to visit a mysterious place called Titan.

I'll be right back.

Hi, I'm Emily Loch Duwala with questions and answers. A listener asked, what will happen to the

Hoygen's probe if it lands in an ocean on Titan? It's not known for sure whether there are seas or oceans on Titan or not.

The Huygens probe, built and operated by the European Space Agency, will spin away from the

Cassini spacecraft on December 25, 2004, and, after free-falling for three weeks,

will enter the dense hazy atmosphere of Saturn's largest satellite.

The probe's main mission is to spend two and a half hours parachuting down

through Titan's clouds, transmitting measurements of the atmosphere and of the

approaching surface, whatever it may be made of.

Hoagan's signals will be transmitted to the Cassini spacecraft,

which will relay them back to Earth.

The data will include images captured constantly during Hoagan's descent.

But will Hoagan's descent? But will Hoagan survive hitting Titan's surface? Stay tuned to planetary radio to find out.

If you go to the headline section of the Planetary Society's home page on the web,

you'll find the first of what will be a series of articles about the hunt for

extrasolar planets.
