Come at Temple One's secrets revealed by Deep Impact. This week on planetary radio. Hi everyone, welcome to Public Radio's travel show that takes you to the final frontier.

I'm Ad Kaplan. The University of Maryland's Lucy McFadden is our happy but utterly

swamped guest. The Deep Impact co-investigator barely knows where to begin with 4,500 images sent back by both parts of that

probe and bundles of additional data. We'll hear what she and the team have

figured out so far. Bruce Betts manages to mix Shakespeare, Fish,

and a new trivia contest in this week's What's Up segment. You just have to hang

around to see what I mean.

And while you're hanging, here's a handful of helpful headlines.

Okay, this one is great.

Everybody knows gas giant planets can't possibly form in a three-star or trinary system, right?

Except a Caltech astronomer has just found one, 149 light years from Earth.

Planets, planets everywhere, and a variable in the Drake equation bites a little more dust.

Details are at planetary.org.

While you're there, you can check out the latest cool images from Cassini, the spacecraft whizzed by within just

170 kilometers, or barely 100 miles from Saturn's icy moon Enceladus.

Looks like it's going to be at least Saturday the 23rd before Discovery can lift off on its return to flight mission.

NASA engineers are still figuring out the problem with the fuel

sensors in the big external tank attached to the space shuttle. What is a ring occultation? Here's a hint.

It has nothing to do with that flawed cubic zirconia

you bought your significant other.

Let Emily help you figure it out.

I'll be right back with Lucy McFadden.
