Night, Day & Night Again

Day to night and back again: Earth's ionosphere during the total solar eclipse

The Summer Solstice takes place between June 20th and 22nd in the northern hemisphere and between December 20th and 23rd each year in the southern hemisphere. The Winter Solstice occurs at the same time but in reverse — between Dec. According to NOAA , around the Winter Solstice at the North Pole there will be no sunlight or even twilight beginning in early October, and the darkness lasts until the beginning of dawn in early March.

Earth’s Rotation:

Conversely, around the Summer Solstice, the North Pole stays in full sunlight all day long throughout the entire summer unless there are clouds. After the Summer Solstice, the sun starts to sink towards the horizon. Another common feature in the cycle of day and night is the visibility of the Moon, the stars, and other celestial bodies. On certain days, when the Moon is well-positioned between the Earth and the Sun, it is visible during the daytime. However, the stars and other planets of our Solar System are only visible at night after the Sun has fully set.

Night and Day (song)

The reason for this is because the light of these objects is too faint to be seen during daylight hours. The Sun, being the closest star to us and the most radiant object visible from Earth, naturally obscures them when it is overhead. On an especially clear night, and assuming light pollution is not a major factor, the glowing band of the Milky Way and other clouds of dust and gas may also be visible in the night sky.

These objects are more distant than the stars in our vicinity of the Galaxy, and therefore have less luminosity and are more difficult to see. Another interesting thing about the cycle of day and night is that it is getting slower with time.
