A distant world wanders the galaxy and PlanetVac heads into space this week on planetary radio.

Welcome, I'm Ad Kaplan, of the Planetary Society with more of the human adventure across our

solar system and beyond.

So much to share with you today.

We'll talk with astronomer Radak Pulaski, whose team has used

Planetary Society CEO Bill Nye will share some thoughts too,

and it's a signed copy of Bill's newest book that someone

will soon win in the What's Up Space Trivia Contest Bruce will announce that pale blue

dot where we all live tops the November 6th edition of the downlink.

You'll find these stories among others below it, beginning with word that there may be as many

as 300 million habitable planets in our own

galaxy alone. We've also learned that the European Space Agency's little

fillet lander carried to Comet 67P by Rosetta tumbled through ancient surface ice that was, and I'm quoting,

fluffier than cappuccino froth.

And if you want to see how our solar system's biggest worlds may have migrated

outward from much closer to the sun, well we've got the video at planetary.org

slash downlink. Here's something that is not in the down-link. It's my

personal thanks to those of you who took a few moments to leave us ratings and
