But what does all of this money and time mean about the power of FAST? Well, according to China Daily, engineers have claimed that FAST is so sensitive that it could detect someone using a cellphone on the Moon. There’s more to the telescope than even that, though. Indeed, within its first year of operation it has already picked up two incredible stellar objects.
Those two objects are called pulsars – neutron stars that rotate at unbelievable speeds. It often takes them each less than a second to spin round a single time, in fact, and they release large pulses of radiation. Moreover, perhaps unsurprisingly, staff at FAST believe that distinguishing the two pulsars in just the first year of the telescope’s life is an impressive feat.
