In part 2 of this series, we look at the supertelescopes heading to space in the next few decades.

In this week’s question show, Fraser wonders if science is the best tool we’ve got, if communicating with aliens is a wise idea, and how he feels about people falling asleep to his videos.

Astronomy is about to get much much more exciting, with a whole new class of enormous telescopes developed on Earth and in space. How much more powerful? What will we be able to see?

The Van Allen Belts surround the Earth with deadly radiation. What can we do to get past them and escape into deep space?

In this week’s question show, Fraser answers questions about dark matter black holes, the magnetospheres of exoplanets and whether the Earth is increasing or decreasing in mass.

In this week’s QA, Fraser worries about artificial super intelligence, getting flung out of the Milky Way.
