On Oct. 14 , a partial"ring of fire " solar eclipsewill be seeable across most of the Americas for the first clock time since 2012 , and a squad of astronomer wants you to revel it as science intended : By break out the old disco clod .
Why ? The first reason is to preserve your visual sensation . You ’re likely aware that staring at the sun , even for a moment , isvery , very bad for your eyesand should be quash at all costs .

Traditionally safe ways of viewing solar occultation include wearing a pair ofapproved solar glass , or viewing the eclipse indirectly with a hand-held eclipse projector such as a pinhole television camera ( a simple twist that’seasy enough to make at homewith some composition board and tinfoil ) . In a collar , you may even hold a kitchen cullender over a piece of paper while the occultation is occurring , and see the shrink crescent of the Lord’s Day draw through each tiny hole in the cullender ’s tail .
These are all safe , proven method acting of occultation viewing — but they miss a sure level of genius and herd appeal , according to the authors of a new paper titled " Why every observation tower require a disco ball , " release Sept. 25 to the preprint database arXiv .

Their argument is simple : Rather than projecting a single figure of asolar eclipseonto a surface , like a pinhole camera does , a discotheque ball reflects lots of identical eclipse icon onto multiple surfaces at once , making them " interesting and unexpected objects for demonstrating purgative to schoolchildren and the general world , " the authors compose .
" Unlike more traditional solar projection tools like pinhole projectors and colanders , the disco orchis spreads its solar figure of speech across a room , producing recognizable solar disks from distances of about 2 metres [ 6.5 feet ] and onwards , " the researchers wrote . " This cause the disco ball a more accessible shaft for larger or socially outdistance groups . "
For best results , simply rate a disco orb near a windowpane with a unmortgaged persuasion of the sun , enabling the illumination to hit as much of the ball ’s surface as potential . Each mirrored facet of the ball — also known as a pinhole mirror — will reverberate an image of the sun ’s disc onto any nearby aerofoil , capturing the progress of the eclipse just as clearly as a pinhole photographic camera would .
