China is building the world's biggest radio telescope to communicate with aliens
Yesterday NASA announced that it had found Earth's twin. When asked how the organization would research whether intelligent life existed on Earth 2.0, NASA replied that it would broadcast radio signals in hopes the familiar planet could intercept radio waves, among other techniques.
In related news, China has started to assemble the world's largest radio telescope. "Having a more sensitive telescope, we can receive weaker and more distant radio messages," said Wu Xiangping, director-general of the Chinese Astronomical Society. "It will help us to search for intelligent life outside of the galaxy and explore the origins of the universe."
Facts about the telescope:
The telescope is a five-hundred-meter Aperture Spherical Radio Telescope (FAST).
Technicians began attaching 4,450 triangular-shaped panels to the telescope's reflector today.
Before FAST, the largest single-aperture telescope was the Arecibo Observatory in Puerto Rico which is 205 meters in diameter.
