Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse. In order to keep your spacecraft alive in that environment, you need electricity to keep it warm. Not to mention all the power to run scientific instruments and the transmitters to send that data home. Getting enough power in space is a big problem.

Humans are believed to be the most technologically advanced civilization that’s ever set foot on Earth, or really anywhere in the Solar System. But are we the first?

In this week's questions show, astronaut Mike Massimino answers a question about astronaut training, I wonder how we could survive if the Sun dies, and explain why the shuttle's fuel tank was orange.

In my opinion, Eric Berger (aka @sciguyspace) is one of the top journalists working on stories about spaceflight, especially SpaceX, Blue Origins and NASA. Eric will join me live to answer your questions about the state of private and public space exploration.

The observable Universe is finite, which means there are limits to what we can see, now and deep into the future. Dr. Paul Sutter joins Fraser to talk about the various cosmological horizons that surround us.
