Hostile Worlds: Exploring Space

• Hello Sunshine | Episode 10

  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 FireOnTheMound.com and StrangeLovePodcast.com And a big thanks to guest cast member Tanja Milojevic for her excellent performance as Dr. Cellarius. You can find Tanja’s own work at http://www.lightningbolt.podbean.com/ (LightningBolt Theater of the Mind). This also brings down the curtain on season one of Hostile Worlds. However, as we gear up to plan season two, we’d love to get your feedback, opinions, and suggestions. You can do that by filling out this very brief survey – we really would appreciate your input  Things to Learn What’s so interesting about the sun’s corona? How deep are the layers of the sun, and how do they compare to distances on earth? Where does the sun’s light actually come from? How many years does it take for the sun’s energy to pass through the radiation zone? What is the Black Dwarf phase, and has it ever happened before? What’s in the cold storage container?

• Here Comes The Sun | Episode 9

  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?

This is the first part of a two-part episode, guest written by friend of the show William J. Meyer. You can find William's own spectacular podcasts at http://www.fireonthemound.com/ (FireOnTheMound.com) and StrangeLovePodcast.com Oh, and don't forget to check out our Hostile Worlds merchandise Store too!

• What Are Brown Dwarfs? Episode 8

  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 also announce details of our brand new Hostile Worlds merchandise store on TeePublic. Want a Hostile Worlds-branded t-shirt, hoodie, poster, sticker, or mug? Then you're in luck! Things to Learn What's the difference between a Brown Dwarf, a star, and a planet? Why are Brown Dwarfs interesting to scientists? Are Brown Dwarfs rare? What makes a Brown Dwarf?

• Exploring Venus | Episode 7

  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 own “Pale Blue Dot” than we realise. Things to Learn • Does Venus have volcanoes? • What happened to the Soviet Union’s Venera rocket series? • Why does a year on Venus last longer than a day? • Why are the plains so flat? • Why is it so hard to see the surface from Earth? • Could we colonise Venus, despite its hostile environment?

• The Life cycle of a Star | Episode 6

  As the crew of The Tardigrade prepare to land on Venus, Matthew heads back down to Earth to get some supplies. Whilst back on the home planet, he pays a visit to St. Andrews Observatory to have a look at the James Gregory Telescope - the biggest telescope in Scotland. The custodian of this fine piece of equipment is Dr. Aleks Scholz, an observational astronomer who studies problems in star and planet formation. This was a good opportunity for us all to learn something new, so Aleks is going to talk us through the life cycle of a star. Things to Learn How do stars from? Why does size matter when it comes to star formation? How do stars die? What determines the ultimate fate of a star? What causes stars to explode? How will our own sun die? What impact will the sun dying have on the planets in our solar system? If Aleks could visit anywhere in the universe, where would he go?
