Radio telescope array might unlock the secrets and techniques of the early universe
To seize the night time sky and higher perceive the youth of our universe, astronomers are utilizing one thing a tad extra highly effective than a standard telescope. The Owens Valley Lengthy Wavelength Array (OV-LWA) leverages 250 radio antennas, unfold over a desert space equal to 450 soccer fields, to detect slender radio alerts produced by distant pulsars, photo voltaic flares and auroras. Collectively, this military of antennas can seize all the sky concurrently and feed the ensuing knowledge again to the Owens Valley Radio Observatory. With over 25 terabytes flowing in every single day, astronomers can research area climate, similar to auroras, which happen when stars launch magnetic power.
It is hoped that sooner or later, the array may also be used to detect traces of radio mild from when the primary stars and galaxies have been born. In the mean time, proof of those occasions is blocked by hydrogen fog, thwarting optical and infrared telescopes, however it’s attainable the OV-LWA will be capable of minimize by means of and supply new perception concerning the early universe.
This is a 24 hour time lapse video of the radio sky captured by the array:
