>> China's powering up the world's largest alien hunting telescope. This massive dish officially beginning operations on Sunday after five years in the making. At 1,600 feet across, it's roughly the size of 30 football fields and much larger than Puerto Rico's Arecibo Observatory, which was the largest radio telescope for half a century.
The telescope known as fast is designed to comb deep space with radar, listening out for whispers of extraterrestrial life. On top of costing around $200 million it had to be carved out of a mountain. Forcing nearly 9,000 people from the surrounding area. Behind scientific discovery the site is meant to showcase China's plan to become a scientific power house.
Chinese president Xi Jinping has made space exploration a top priority. Deploying a lunar rover in 2013 and aiming to put a man on the moon within two decades. Scientist's will start calibrating the giant telescope this week, but it could be years before it's fully operational. Sending out beams to scan for pulsars, gravity waves, and any sign of life beyond our world.
