Houston, we have a podcast.

Welcome to the official podcast of the NASA Johnson Space Center, episode 359,

Astrobiology.

I'm Dane Turner, and I'll be your host today.

On this podcast, we bring in the experts, scientists, engineers, and astronauts all to let you know what's going on in the world of human spaceflight and more.

On this episode, we'll discuss aliens of little green men.

Well, not exactly. But the subject of life somewhere

among the stars is something that powerfully captures the human imagination. More so than that,

there is a scientific field that looks at life in the stars.

The study of the origin, evolution, and distribution of life in the universe,

astrobiology, is a complex and nuanced field.

We won't be necessarily discussing extraterrestrials directly today, but we will be talking about

the signs that we're looking for that help show that maybe we aren't alone in the universe.

To help us on this journey, we have Becky McCauley Wrench, a program scientist in the Planetary

Science Division at NASA Headquarters.

She is the acting program scientist for the

astrobiology program and leads the Habitable Worlds program,

which we'll be discussing more later.

So watch the skies and let's look for signs of life. P-M. minus five, second to County.
