This news came to me via Amateur Radio Weekly.
Some years ago the huge radio telescope at Arecibo in Puerto Rico failed terminally when some of its cables broke. It is not going to be repaired.
China has built a larger and more sensitive dish in a project called FAST. I had no idea about this. As far as I can tell, it puts China far ahead of the USA in space exploration. It is built in a remote region of China and has a radio-quiet area of 5km around the dish. It can detect very weak signals, far weaker than those that could be detected at Arecibo.
