Combining the recorded signals, it will be possible to obtain a collecting area equivalent to the one of 1 square kilometer parabolic antenna. Radio telescopes of increasing size and sophistication were built first in Australia and Great Britain and later in the United States and other countries. The antenna was placed on a natural depression in the ground and it has no mount: the radio telescope can point different sky regions moving the central feedhorn. Parkes (Australia) Parkes Observatory is located in the south-eastern Australia and it uses a great 64 meters diameter parabolic antenna. This will eclipse what had been the world’s biggest telescope, in the Arecibo Observatory in Puerto Rico. The gigantic radio telescope will cost £120m to build and will allow scientists to detect weaker radio signals from beyond our own solar system. The telescope is made up of 4,450 reflective panels. The bowl has a diameter of 76.2 metres and became operational just in time for the launch of Sputnik 1, the world’s first artificial satellite, and the telescope took part in some of the early work of satellite communication. Since the wavelengths being observed with these types of antennas are so long, the "reflector" … China is assembling what has been hailed as the world's largest radio telescope, state media reported.
