Photography : Astronomy : Cloud Signals

The Very Large Array is an array of 27 radio telescopes a few hours North of Las Cruces, and I had the privledge of visiting there and using it to get data. Each dish is 82 feet (25 m) across and they can be arranged along tracks in a Y-shape. By combining the signals from the telescopes scattered along this Y track, the VLA acts like a radio telescope 22 miles across (36 km) and 422 feet wide (130 m). On this windy day the clouds looked like they were waves beaming down into one of the dishes.
