    Hello Sunshine

    Hello Sunshine

    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  very brief survey (http://www.lightningbolt.podbean.com/)  – we really would appreciate your input

    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?

    Here Comes The Sun

    Our lives literally revolve around it. That big yellow ball in the sky - The Sun.

    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. Meyer. You can find William's own spectacular podcasts at Hostile Worlds merchandise Store (http://www.fireonthemound.com/)  too!

    Exploring Venus

    Exploring Venus

    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.

    • 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?

    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.
