An incredible portrait of a stellar nursery this week on planetary radio. Hi everyone, welcome to Public Radio's travel show that takes you to the

final frontier.

I'm Matt Kaplan. You've seen the Orion Nebula, right? If not directly through a

telescope, then is one of the images captured by the Hubble Space Telescope or one of its

terrestrial cousins. Ah, but you've never seen it like this.

Massimo Roberto of the Space Telescope Science Institute

will be our guest and guide

as we explore a brand new 1 billion pixel picture, the biggest ever

assembled from the Hubble. We also hope you'll stick around for what's up.

Bruce Betts is back in person this week offering another chance to win the

new Explorer's Guide to Mars poster in the space trivia contest. The search for

another Earth is getting warmer and warmer. That's the story at the top of our news

this week with the discovery of the smallest extrasolar planet yet. Maybe warmer

and warmer isn't the right description since this new rocky ball is pretty frigid,

but it is only about five times as big as Earth.

The details are in an ice article by my colleague Amir Alexander.

You'll find it at planetary.org.

Meanwhile, Mars seems to be getting more Earth-like every day.

Did you hear the report from researchers at Brown University?

They think the Red Planet once had glaciers.

That's right, glaciers.
