When it comes to telescopes, bigger is better. But bigger is more expensive. Way more expensive. To keep the costs reasonable while improving the sensitivity of their instruments, astronomers use an amazing technique called interferometry. Instead of building a single huge telescope, you can merge the light from several telescopes to act like a much larger telescope. It's a technique that has already revolutionized Earth-based observing - but just wait until it gets into space...http://feeds2.feedburner.com/~r/astronomycast/~4/uyRvNgYhXec

I LOVE Astronomy Cast. Its my favorite podcast. But I will have to say that I just did not understand the explanation of interferometry. This is the only time its happened. You guys are usually terrific at explaining complex issues in ways that even simpletons like me can understand.
