How can we see stars as they first come into being? This month, we’re looking at ALMA – the Atacama Large Millimetre Array – possibly the most complicated telescope to date, that promises to peer into star forming regions.
Plus, we chat to some of the winners of the 2012 Astronomy Photographer of the Year competition, and find out what it takes to start taking pictures of the heavens.

27:37 - The Astronomy Photographer of the Year 2012
Ever looked up at a pristine night sky, and wanted to take that image home with you, to forever remind you of our place in the universe? Sadly, it’s not as simple as pointing a camera upwards and pressing the button – taking photos of objects in space – or astrophotography – is...

42:39 - Can you generate light with a radio antenna?
I understand that light and radio are very much the same kind of thing. Yet the equipment we use to generate visible is very different from that which we use to generate radio. Why is that? Could you generate visible light from apparatus similar to that used to transmit radio? I....

Why do all planets revolve around the Sun in almost the same plane?
54:44 - Is light blue-shifted by gravity?
Dear Naked Astronomers,
When we send probes into space, we use gravity assists to speed it up. If a photon of light were to pass by a large body, such as Jupiter, instead of going faster (since the speed of light is constant), could the beam get blue shifted?
