The Italian National Institute of Astrophysics ( INAF ) has unveil the ASTRI undertaking , the first prototype for a newfangled low - monetary value , earth - base scope that   will look at gamma - ray expelling from the sky .

The observatory , which is located on the side of Mount Etna , was able to go its most unmanageable trial yet on October 16 . The telescope was capable to keep its angular settlement constant over a encompassing theatre of operations of persuasion . This is a important necessity for Vasco da Gamma - light beam telescope .

Gamma - shaft do n’t penetrate our standard atmosphere but interact with the gas atom present , engender a shower of subatomic particles that   move faster than light in air ( but still slower than light in a vacuum ) . Moving so fast , they emit what is have it off as Cherenkov light , which is what this telescope isdesigned to look for .

" The telescope was built and completed for the first sentence ever adopting the Schwarzschild - Couder conformation , " articulate Giovanni Pareschi , stargazer at the INAF - Brera Astronomical Observatory and principal research worker of the ASTRI project , in astatement . " This form of telescope has never been pull in until now , chiefly due to technical difficulties . "

This scope model was first purpose by Karl Schwarzschild in 1905 and the design was then enhanced by André Couder in 1926 . Its two mirrors were design to eliminate most of the optical aberrance in the athletic field of view , but it was too difficult and expensive to actually build .

“ However , recent advances in engineering science ( in special for the realization of the primary and lower-ranking mirror ) have made the implementation of this design feasible ( thanks also to the study by Prof. Vladimir Vassiliev at UCLA ) for the observation of Cherenkov light emitted by the atmospherical showers generate by cosmic Vasco da Gamma rays , ” add together Pareschi .

ASTRI is the harbinger for theCherenkov Telescope Array(CTA ) , the next contemporaries of gamma - light beam observatories that   will have more than 100 telescopes across two sites in both hemispheres . ASTRI is one of the Small Size Telescopes , and the CTA anticipate to have 70 of these telescopes between both sites .

The scope is expected to honour the first Cherenkov brightness next calendar month .
