A Square Kilometer

To peer deeper into the bowels of the universe we need to take the next big step in radio astronomy.  How about one that's a square kilometer?  No, that's not the size of the paddock, that's the surface of the collecting area. We're talking about a big project. Think the Snowy Mountains scheme, think the Large Hadron Collider. Big. Australia is in the running to host the SKA. Special guests today, Prof Frank Briggs, and David Reneke.  Hosted by Rod with thanks to Annie Harris.
