Not-so-serious Sunday 27

In the light of his recent appearance on the ABC Breakfast show explaining the solar eclipse I thought we should revisit one of Charley Lineweaver‘s other great interviews, about the Transit of Venus. Charley is one of the researchers at RSES and looks at various planetary, cosmological and astro-biological topics, including extra-solar planets as well as quickly being the goto guy for ABC News Breakfast on all things space related.
