hi! i have two questions...would appreciate if could get answers or sources to go to.

How do the telescopes(radio or optical) in an array act as a single telescope? what is the technic, math, enginering, logic behind it.

How is the data from a radio telescope translated into a picture? The color is assigned. That is fine but is the sky photographed in x-ray or gamma rays just like the way a photo is taken in the visible spectrum or is the data-frequency, more like oscillating lines showing the changing frequencies- translated into photoes...in short: What is the process? How does a radio telescope work? how is a photo developed from the data collected? With thanks, N

A good starting point for answers to your questions can be found
at the National Radio Astronomy Observatory (NRAO) website.

Be sure to check out the FAQ and How Radio Telescopes Work.
