Nevermind Arecibo Observatory in Puerto Rico broke, China just made this in record time.

The telescope was officially put into service on January 11th, 2020. However, it started observations well before then and has so far imaged 240 pulsars. One of the most significant was found in the Messier 92 star cluster. It’s a so-called millisecond pulsar that spins much faster than normal pulsars at an incredible 316.5 rotations per second (18.990 RPM), while sucking in and ejecting matter from its companion star.

China’s Sky Eye is the largest FAST telescope in the world and the only one that can do specific types of observations following the collapse of the Arecibo Observatory radio telescope in Puerto Rico. The US National Science Foundation said it would tear down the observatory, but there’s some glimmer of hope it may be rebuilt after Puerto Rico pledged $8 million in aid.
