In a picture issued on Feb. 8, 2019 the white glow of zodiacal light is visible in the night sky as photographed near Hajnacka, southern Slovakia on Thursday, Feb. 7, 2019. The faint light is caused by interplanetary dust reflecting sunlight. The astronomical phenomenon in the temperate zones is most clearly visible in February and March after sunset and in September and October before sunrise, when the zodiac is positioned at a steep angle to the horizon.
