Radio telescopes , which you may rememberJodie Foster intently listening to for signs of foreign life inContact , pluck out wireless waves from far out space . Ordinary communications satellite dishes also foot up radio receiver waves , but of manmade origin . So hmm , how well can you convert one into another ? It ’s altogether potential , harmonise to New Zealand uranologist who detail how theyturned an obsolete artificial satellite bag into a wireless scope for astronomy .
In 2010 , Telecom New Zealanddecommissioned one of its satellite antennas . ( Satellite dish are basically parabolically mold antenna . ) The 80s era transmitting aerial had once carried phone shout , internet dealings , and goggle box , but it was being replaced by underground fiber . Plus , it was old and rusty , made all the uncollectible by salt from the nearby ocean . But the 30 - beat ( or 98 - feet ) dish was still a massive patch of substructure that worked , so they donated it to astronomer at the Auckland University of Technology .
A paperrecently posted on ArXivgoes into precisely how a 30 - yr - old dish became a radio telescope useful for modernistic astronomy . The first step was just replacing the rusty bolt . Then they replaced the dish ’s pointing mechanism , so it could rick the full 270 degrees for radio set uranology , up from 170 degrees before . The aerial also had to be retro outfit to pick up frequencies relevant for listening to distance rather than listening to tenacious - length phone call .
The converted antenna could work alone or as part of a larger regalia . “ This 30 m antenna add up significantly to New Zealand ’s capability in receiving set uranology with a large Earth’s surface arena and is a extremely sensitive legal document open of substantial single dish workplace , ” publish the author in the newspaper publisher . Elsewhere in the macrocosm , including Japan and Australia , satellite antennae have been work into radiocommunication telescope .
For the rum among you who do n’t have a 30 - metre artificial satellite antenna lie around , despair not . Here ’s how to make a “ poor man ’s radio receiver scope ” from a regular old satellite smasher . In fact , here ’s another moresophisticated version . You probably wo n’t be the first to find out any stranger on it , but you may definitely impress some humans . [ ArXivviaTech Review ]
