Astronomical research: Tomorrow is the shortest day and the longest night in Egypt, coinciding with the winter solstice

MENA Agency:

Professor of Astronomy at the National Institute for Astronomy and Geophysical Research, Dr. Ashraf Tadros, said that today, Wednesday, will be the shortest day of the year.

and the longest night, as the length of the day reaches only about 10 hours, while the night lengthens .

and reaches approximately 14 hours, coinciding with the occurrence of the inversion phenomenon, Winter in Egypt and the countries of the northern hemisphere.

Tadros indicated that on this day, the sun will reach its lowest height above the horizon at noon when it crosses the meridian, and the human shadow on Earth at this moment will be the longest possible.

He explained that the winter solstice means the height of the winter season, and this year it takes place in Egypt.

on Wednesday at 11:48 pm local time in Cairo, pointing out that the number of days of winter this year will be about 89 days, 20 hours and 44 minutes.

He said that the winter solstice is an astronomical phenomenon that occurs when the sun is in the sky at the lowest angular distance from the horizon.

and after a day of it, the sun begins to ascend to the northeast in its apparent movement, as the length of the night decreases and .

the length of the day increases until night is equal to day on March 21, It is the date of the spring equinox.

And he added that the day of the winter solstice is characterized by a late sunrise and an early sunset that is, a short day and a long night.

This is what happens gradually since the beginning of December of each year until the moment of the winter solstice comes, in which the sun is located directly over the orbit of Capricorn in the southern hemisphere.

Earth, and the sun is apparently at its maximum inclination towards the south, as the North Pole tilts away from the sun by 23.5 degrees.

and the length of the day in all locations north of the equator will be less than 12 hours.

He explained that it is known astronomically that the Earth does not rotate completely vertically around itself.

but that its axis of rotation deviates by 23 and a half degrees, and therefore the amount of energy that the Earth receives from the sun is variable in the northern .

and southern halves of it, stressing that it is a common mistake to say that “it is summer.”

And winter arise as a result of the proximity or distance of the earth from the sun, but its scientific fact is that summer.

and winter arise due to the deviation of the earth’s rotation axis around itself by 23 and a half degrees.

It is noteworthy that Egypt will witness tomorrow, Wednesday, 5 distinct astronomical phenomena.
