To the edge of the universe and beyond this week on planetary radio.

Welcome to the travel show that takes you to the final frontier. I'm Matt Kaplan of the Planetary Society.

0:22.0

They call it the Super Bowl of Astronomy, and this year the American

0:26.2

Astronomical Society brought its annual meeting to my hometown of Long Beach, California.

0:32.2

We'll get a tiny sample of the 1900

instruments too much. And so most of the cool stuff is on the cool side of the spacecraft, so to speak.
