And the reason that it's blinking is because there are planets that are going past it all the time, and it's that special orientation where the planets are blocking the light from the star that allows us to see that light blinking.
I la raó per la que centelleja és perquè hi ha planetes que van passant per davant constantment, i está orientada de tal manera que els planetes bloquejen la llum de l'estrella i ens permet veure aquest centelleig.
