Sit away from the lights, lie down, observe the sky and make wishes. Several streams of shooting stars will cross the sky in October. This is the case this weekend with the capricious Draconids. This phenomenon is also visible during other times of the year, explains Christian Manasterski, member of the Neuchâtel Astronomy Society. This is the entry of a comet into Earth’s orbit. She left debris there, because with the heat of the sun, the ice melts and there are small rocks that remain suspended in space. And there is a moment, it’s now, where the earth crosses this cloud of debris. This is what forms shooting stars. »

As you have noticed, some shooting stars are brighter than others. This phenomenon is essentially explained “by the size of the objects which impact the earth. There are small ones which leave very weak light traces and larger ones which leave significant light traces. » To get the most out of the show, you have to wait for your eyes to get used to the darkness, so you have to stay in the dark for around ten minutes. Then, you have to look north, in the direction of the Dragon constellation. A constellation located next to the North Star. /sma
