This is the Kepler Telescope it is used to find habitable planets in the Kepler region (See Above). It sends a signal into the region then that signal gets interupted by a "planet". This is infact a real telescope it is orbiting in our solar system. The bronze colored metal is brass it is creating a faraday cage to block out signals to inturupt with the telescopes internal system. There is lots of radiation in space so the bronze is inturupting those signals.
