Sorry for the lack of a Hangout last week, we had massive internet fail in Fraser's home city.

This week, we talk about: Building a real starship Enterprise, preparations for the annular solar eclipse, investigation into the Gaia theory, fuel for black holes, Hubble and the transit of Venus.

We're joined by Amy Shira Teitel, Jason Major, Nancy Atkinson, Nicole Gugliucci, Phil Plait.
