Why Do Radio Telescopes Need Dozens of Dishes?
<p>Giant dishes are not built for radio telescopes for two reasons. First, it’s challenging to achieve the necessary precision in construction. Already at a diameter of 100 meters, significant deformations occur due to the dish’s weight, the impact of wind, etc. If the dishes were to be made even larger, their cost would become simply prohibitive for any country.</p>
<p>Secondly, all practical astronomy is based on a principle that holds for any telescope: the larger its lens/dish, the fainter the objects it can discern, and the higher its resolution. However, unlike conventional optical telescopes, radio telescopes can outsmart this principle.</p>
