Stuff You Should Know
Doin’ Science in the National Radio Quiet Zone

They're saying that this is an area where radio emissions of any kind are heavily regulated, frowned upon you might even say, and the whole reason they're doing this is to protect

The delicate telescopes, radio telescopes used in radio astronomy at a specific place called Green Bank, West Virginia.

They've established a whole zone around it that's meant to block out or keep out radio transmissions so that the astronomers can go about their business happily.

We had radio telescopes, which are very similar.

That's basically it.

But the really amazing thing about what some of these radio telescopes can do, just to give you an idea of how sensitive they are, they measure...

The incoming radio waves that are so weak, they measure them in micro Jansky's, which is a micro Jansky point.
