need to study gamy - energy particles streaming through the macrocosm at nigh the speed of visible light ? There ’s an app for that .
It ’s call in the Distributed Electronic Cosmic - Ray Observatory ( DECO ) , and unlike the huge , multimillion - clam corpuscle detector housed in labs , DECO allows smartphone owners to turn their phone into a scoop - sizecosmic - beam of light speck detectorby download two apps and sticking a piece of music of duct mag tape over the television camera lens to freeze out light subatomic particle .

" The apps basically metamorphose the phone into a high - energy subatomic particle detector , " Justin Vandenbroucke , a physics prof at the University of Wisconsin - Madison and Jehovah of the apps , articulate in a statement . " It uses the same principles as these very gravid experiments . " [ In simulacrum : Utah ’s Cosmic Ray - Finding Telescope ]
Cosmic rays are still a mystery to astrophysicists . There ’s a Brobdingnagian number of them flying through the cosmos and astronomers think they come from herculean force like black jam and exploding supernovas .
wave of cosmic shaft are forever come apart against the Earth ’s air . Whencosmic raysrain down on the planet , they secrete a flood of high - energy molecule . Most of the particles are proton , but they also contain a cocktail of other particles , include electrons and heavy nuclear nuclei , which are the thick centers of particle dwell of proton and neutrons . Some scientist think these particles could discover more about the mysteriousdark matterthat is thought to make up around 27 per centum of the universe .
One eccentric of corpuscle discover in cosmic rays is the mu-meson . DECO can detect negative muon by taking reward of the Si chips embedded in smartphone cameras . Digital television camera grow mental image by record the short particles that bump off them , but when negative muon particles hit silicon in a photographic camera , they give off an electric signal . This signal shows up as a pixel touch . DECO is design to snap a movie every few seconds and scan for any particle pixel key signature . If pixel signature are discover , then the app saves the exposure and logs the image .
Muons are weakly interacting molecule . They can pass through most materials like ceilings and walls , so a smartphone launch the DECO app could catch molecule information from anywhere . During his mental testing , Vandenbroucke ran the app during long - distance flight , since muons are well-to-do to notice at mellow altitudes .
Smartphone apps can not replace the sensitivity and precision of larger , more sophisticated molecule detectors . Instead , DECO is geared more toward didactics and citizen science , Vandenbroucke say .
in good order now the apps are usable for only Android phones , and users need to download both thedata logger appand theDECO appto start collecting cosmic shaft particles .
