The world's largest radio telescope began operating in southwestern China Sunday, a project Beijing says will help humanity search for alien life. The Five-hundred-metre Aperture Spherical Radio Telescope (FAST), nestled between hills in the mountainous region of Guizhou, began working around noon, the official Xinhua news agency reported. Built at a cost of 1.2 billion yuan ($180 million), the telescope dwarfs the Arecibo Observatory in Puerto Rico as the world's largest single-dish radio telescope, with twice the sensitivity and a reflector as large as 30 football fields, it said.
Britain's parliament must be kept fully informed about the government's strategy for leaving the European Union, Jeremy Corbyn, leader of the main opposition Labour Party, said on Sunday. Prime Minister Theresa May has said parliament would play a role in Britain's exit from the EU but that she will be leading the negotiations and will make the final decision on what deal the country gets. Asked by the BBC's Andrew Marr whether that was democratic, Corbyn said: "I don't think it's democratic and I don't think it's sustainable at all." "This is a huge political issue, it's the most significant economic issue facing Britain in my or your lifetime and I think at the very least parliament should be fully informed." He said Labour had set up a Brexit team to demand information from the government and also get involved in talks.
