There are twenty seven 230 ton, 25 meter wide dish antennas place along three legs of a Y shaped antenna grid that is 22 miles across. They act together as one very large telescope. Radio waves are generated by nearly every object in space, but they are a billionth of a billion times less powerful than a call on you cell phone. In fact, cell phones must be turned off as they can blind the telescope's sensitive radio eyes.
The resolution of the VLA can be varied by changing the distance of the dishes from the center. They are move four times a year.

The LVA is its' self a star. It was featured in Carl Sagan's Comos: A Personal Voyage, and the films 2010, The Arrival and Independence Day to name a few.
