Zodiacal Light: The faint conical glow of the Zodiacal Light,produced by reflection and scattering of sun-light from countless small particles lying in the ecliptic plane, is an elusive sight in our light-polluted times. If you stand on the moon, you see earth only from one side of the moon. Also note that up to 65 degrees latitude the sun rises and sets daily.

Look in the table, that even at 70 miles away from the pole, there are 10 days when sun rises and sets. But at higher latitudes (Polar region, like Norway, Finland, and Alaska) the highest and lowest point occur below horizon in winter (meaning several months long night), and above horizon in summer when the sun never sets for several months (meaning several months long day).ДЄctually, except for poles, no where is the 6 months long day and 6 months long night. At temperate latitudes, the highest point is visible but lowest point is below horizon. However, there comes a time in every day when the sun is at its highset point (Noon) and at lowest point (Midnight). Polar regions like Norway, Finland, and Alaska have areas where the sun stays below horizon for several months in winter, and stays above horizon for several months in summer. To apply this concept an iterative calculation process is used by decreasing the latitude by 0.1 degrees keeping the longitude the same and recalculate Sunset time and repeat this process until a latitude is reached where the sun sets and that latitude and same longitude is used. To calculate Maghrib, Isha and Fajr for higher latitudes where the sun does not set or does not rise, uses the Fiqh concept of 'Aqrabul-Bilaad'. For places at higher latitudes, in some months the sun does not set or does not rise.

The times for Zuhr and Asr are observable for all places on earth and can be easily calculated.
