The world ’s largest wireless telescope is officially online . Commencing its first intensive testing phase , Chinese scientist have confirmed that the huge 500 - meter - wide ( 1,640 foot ) dish has received its first signals from deep space .
Although it will take three more long time to finely calibrate the enormous legal document , its activation marks an important moment in astrophysical research – not just for China , but for the world . Dwarfing the former phonograph record holder – the Aricebo Observatory in Puerto Rico – by almost 195 meters ( 640 feet ) , theFive Hundred Meter Aperture Spherical Telescope(FAST ) scope in Guizhou Province will be able to appear for mysterious radio signals across the night sky like no other musical instrument .
It will be able to take in signals from nearly unfathomable distances , and science ’s understanding of some of the most energetic object in cosmos , from pulsars to quasars , will meliorate drastically . FAST will aid in the search for sources of elusivegravitational wavesalongside the ultimate prize – the search for signs of extraterrestrial life-time .
“ The ultimate goal of FAST is to discover the laws of the development of the creation , ” Qian Lei , an associate research worker with the National Astronomical Observatories of the Chinese Academy of Sciences , told Taiwanese State Department broadcaster CCTV , as reported by theAssociated Press .
FAST , which is nicknamed Tianyan ( “ Eye of Heaven ” ) , incur its first receiving set signals from a pulsar 1,351 unaccented - years aside from Earth . Pulsars are rotating neutron stars , extremely magnetized remnants of the core group of collapse massive star . mail out a radio beam of electromagnetic actinotherapy as they spin , they act as the “ pharos ” of the universe .
When the first pulsar was discovered in 1967 by astrophysicist Jocelyn Nell Burnell and radio astronomer Antony Hewish , it was ab initio given the designationLGM-1 , which stand for “ Little Green Men . ”
At the time , such precisely rhythmic radio signals appear to harness out any natural phenomenon , and it was hypothesized – albeit with a heavy catch of salinity – that this strange signal pattern could have been generated by an advanced alien civilisation notifying the cosmos of its world . Although it was later confirmed to be the first discovery of a pulsar , the foreign signal comparing was n’t lost on researchers , and even those working at FAST are keeping it in mind today .
“ In possibility , if there is civilization in knocked out space , the radio set signal it send will be similar to the signal we can receive when a pulsar is approaching us , ” Qian told CCTV .

tight is part ofChina ’s driveto become one of the world ’s scientific powerhouse . In terms of skill disbursal and paper output , it is second in the world , just behind the US . This $ 180 million astrophysics labor is part of a drive to consolidate the Carry Nation ’s scientific prowess .
Far from securing its own noetic and technical bequest , however , the squad behind the task is keen to open it up to international collaboration . As with many project around the world , this is another beautiful showcase of how skill , unlike politics , knowsno boundary .
“ As presently as the scope works normally , a committee will distribute watching sentence according to the scientific economic value of the proposals , ” the project ’s principal scientist Professor Nan Rendong toldBBC News . “ Proposals from foreign scientists will be accepted and there will be strange scientists on the apportioning commission . ”
With twice the predisposition of the Arecibo Observatory and with up to 10 times the surveying speeds , this Chinese radiocommunication scope is one of humanity ’s most carving - bound way of unknot themysteriesof the population . Who know – maybe FAST will be the agency in which we finally do bring out somelittle green menout there say hello .
