This is Hotel

This is Hotel Mars. I'm John Bachelor David Livingston.

Dr Space of the Space Show as my colleagues and co-host and co-pilot, we're very pleased to travel 40 light years

from the planet Earth troubled as we are, to a star called Trappist and to a planet on Trappist called Trappist, Trappist 1B, orbiting Trappist.

And Trappist is a particular kind of a star

and acquiring information about the star and his planetary system.

It requires an explanation and that's why we have Dr. Ryan McDonald with us.

He is a NASA Sagon fellow and astronomer. the Department of Astronomy University of Michigan.

Ryan, it's a great pleasure to welcome me to the show.

Forty light years out is a star called Trappist. It's an ultra-cool dwarf and it has a

planetary system around it consisting of a rocky planet. Is this news? Did we know that little bitty dwarfs can have a

planetary system like great big red giants? Good evening to you, Ryan.

Very good evening to you, John and David. So yeah yeah Trappis 1 is one of the most remarkable planetary systems that we have discovered.

There are seven rocky planets all of which are orbiting far close to this red dwarf star than mercury around our own sun.

And because this star is so much colder than our own sun,

the Habitable zone is much closer.

And actually of these seven planets, three of these rocky

planets are in the habitable zone. So we discovered this system back in 2016 and

since then there has just been a flood of discoveries about these planets and what I'm

excited to talk to you today about is our first GWST observations with the James

Web Space Telescope looking at the pilots in their system.

David, you have a question?
