Hostile Worlds: Exploring Space

Hostile Worlds: Exploring Space

Join us on a journey to some of the most inhospitable, humbling, and frighteningly beautiful places in the known universe. Hostile Worlds is a podcast that lets you explore alien landscapes and extra-terrestrial terrain - all from the comfort of your headphones. From the freezing hydrocarbon oceans of Titan, to the scorched, and suffocating wastes of Venus – we’ll take you on an educational and immersive audio tour to all the places you’d die to see… and places you’d die if you saw. You’ll join the crew of The Tardigrade, an all-purpose vehicle that can float, fly, dive, and dig through any environment in the universe. And you’ll learn all the facts you'll ever needed to present yourself as THE space exploration authority down your local pub on a Friday night. Hostile Worlds is a unique documentary/audio drama hybrid – brought to you by the folks at ThePodcastHost.com

Hello Sunshine | Episode 10

November 19, 2018 • 22 mins
In the last episode, we left a doomed Sarah, David and Dr. Cellarius as they plunged helplessly into the sun. But their inevitable deaths will not be in vain. We’ll still have some time on this episode to learn about the structure of our main star before they reach the core and get burned to crispy cinders. This is part two of our guest-written episode by William J. Meyer. And you can check out William’s own work at FireOnTheMoun...

Here Comes The Sun | Episode 9

June 7, 2018 • 23 mins
Our lives literally revolve around it. That big yellow ball in the sky - The Sun. But what do we really know about El Sol? Is it just a big ball of gas and flame? Or is there more to it than that? On this episode, Sarah and David venture into the Sun's corona, to meet with Dr. Andrea Cellarius. A very bright and flame-boyant scientist. This is the first part of a two-part episode, guest written by friend of the show William J. M...

What Are Brown Dwarfs? Episode 8

April 4, 2018 • 11 mins
The Brown Dwarf. Is it a star? Is it a planet? Is it a tabletop war gaming miniature? Is it an obscure Red Dwarf fan fiction series? We need speculate no more, as observational astronomer Dr. Aleks Scholz of St. Andrews Observatory returns to the podcast with a detailed answer for us. We also announce details of our brand new Hostile Worlds merchandise store on TeePublic. Want a Hostile Worlds-branded t-shirt, hoodie, poster, sti...

Exploring Venus | Episode 7

February 20, 2018 • 22 mins
Welcome to Venus, the second planet from the sun and the closest other planet to Earth. So, why do we always think of Mars as the closest and likeliest candidate for off-world exploration and habitation? On this episode, Sarah and David head to the only planet named after a female deity. With Sarah at the controls, David explores the surface of a planet which, despite its “hot and hellish landscape”, has more similarities to our ...

Surviving in Open Space | Episode 4

November 16, 2017 • 14 mins
Since leaving Titan last month we’ve been doing a bit of deep space exploration in The Tardigrade. And although space can look a bit… empty, it’s actually as hostile an environment as you’re ever likely to find. Out here we’re totally reliant on some pretty fragile materials and equipment keeping us alive. I’m sure everything will be fine of course, but what if something did go wrong? On this episode we’ll create a simulation t...

Magic Islands, Cryovolcanoes, & Electric Snow | Episode 3

September 25, 2017 • 33 mins
Welcome to Titan, the biggest moon of Saturn, and the only known cosmic body other than Earth, that we know for certain has actual lakes and seas on its surface. But that isn’t the only reason that makes this frozen moon such an interesting and fascinating place. On this episode, our crew leave the comfort and warmth of our ship, The Tardigrade, to explore the surface of Titan. Their mission is to report back on the curiosities ...

A Titan Looms | Episode 2

September 8, 2017 • 28 mins
The Tardigrade is on its way to Titan, the biggest moon of Saturn. We're about to break through its hazy orange atmosphere and land on its surface. Our ship won't be the first human-built device to land on Titan though. The Huygens probe made this place its home back in 2005, when it was dropped off here by the Cassini spacecraft. The Cassini-Huygens mission has taught us so much about this fascinating region of the outer solar ...
