“Odd Signals” –Inside Story of China’s Search for Alien Life

“China is a nation fascinated by space exploration and the possibility of finding advanced alien life, whose appearance might be imminent, says Liu Cixin, China’s preeminent science-fiction author of The Three-Body Problem.”

“China’s FAST radio telescope, with a dish the size of 30 football fields, measuring 500 meters in diameter, dwarfing Puerto Rico’s 300-meter Arecibo Observatory, will launch its astronomers into the nation’s role as the new space superpower cinched with its epic landing of the Chang’e-4 Rover this week on the Moon’s far side. FAST could double the known pulsar tally of 2,000, says Peng Bo, FAST’s deputy manager and acting observatory director. It’s also ideal for mapping gas clouds between stars and for listening for signals from alien civilizations.”

“Due to the limitations of current radio technology, Vakoch observed, any radio signals from alien civilizations detected by the dish would have to be strong and deliberately sent with contact in mind, rather than randomly fired out from radio or TV equivalents. “We’d only be able to find the sort of signals that FAST will be looking for: narrow band signals, something that would have a lot of energy put into a carrier,” he said. “An interstellar beacon saying: We are here.”

“Our civilization has only been evolving for tens of thousands of years,” said Dick Manchester, a radio astronomer at Australia’s Commonwealth Scientific and Industrial Research Organisation, Manchester in a discussion with Motherrboad.com. “Other civilizations could have had billions of years to evolve. It’s virtually certain that any other civilization we detect would be enormously more advanced than we are. Our history in terms of stellar evolution is absolutely tiny.”
