The Discussion: Looking back over Sirius Astronomy outreach events in June, a bit of a rant over peer-review and science by press conference and our own pathetic attempts to get awarded a Nobel Prize or two.

The News: Modelling of Pluto's moon Charon ahead of the flyby of NASA's New Horizons spacecraft next year, aerobraking an orbiter through Venus' upper atmosphere and radio imaging a Near Earth Asteroid.

The 5 Minute Concept: How comets are far from the traditional portents of doom and may well be the harbingers of life.

The Interview: Beginning a regular series of interviews with Dr Joe Liske about each of the key facilities in the European Southern Observatory's arsenal, starting with the 3.6 meter telescope.

Q&A: Listeners' questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month Ralph & Paul answer:

• Hey you mad martians, I have a question for the podcast. When we look at other galaxies we can clearly see the glowing bulge at their centres. Why is it when we look up at the milky way we don't see one. Thanks for all your efforts? Lee Garner from Norwich, UK via Facebook .
• Should the BICEP2 team have made their announcement pre-peer review? Mark Cullen (@Mokwepa) from the Buckinghamshire, UK via Twitter .

And we finish with a competition to win a DVD copy of the new film Gagarin – First in Space
