Meteors "Bears" The skies of Egypt are decorated in conjunction with the winter solstice… tomorrow
Dr. Ashraf Tadros, professor of astronomy at the National Institute for Astronomical and Geophysical Research, said that coinciding with the occurrence of the winter solstice in Egypt and the countries of the northern hemisphere, tomorrow, Saturday, “bear” meteors will decorate The sky, starting from tomorrow night until Sunday dawn, is a wonderful astronomical spectacle that can be seen with the naked, healthy eye if the atmosphere is clear and the sky is free of clouds, dust, and water vapor.
Tadros explained, in A statement by the Middle East News Agency today, that the “bears” meteors Of the light meteor showers, the number of meteors in them is about 10 meteors per hour, pointing out that these meteors are produced by dusty debris scattered along the orbit of comet Tuttle, which was discovered in 1790, and the pinniped meteors fall as if they were coming from the Ursa Minor constellation. Minor (near the polar star), which is the reason for its name.
He added that the timing The annual occurrence of this shower is from December 17 to 25 of each year, and it reaches its peak on the night of December 21 and the dawn of December 22.
Regarding the reasons for the appearance of meteors, the astronomy professor at the institute said that meteor showers The annual cycle occurs when the Earth, during its orbit around the Sun, passes through dense gatherings of dust and pebbles scattered along the orbits of comets and asteroids, where they collide with the top of the Earth’s atmosphere and burn up at high altitude. It ranges between 70 and 100 kilometers and appears to us as a strip of light, and this leads to the occurrence of meteor showers that are repeated on an annual basis.
He confirmed that the appearance of these meteors in the sky has no meaning It is harmful to humans or their daily activity on Earth, as it enters the atmosphere and burns up in it at an altitude of more than 70 kilometers from the surface of the Earth. Its observations are enjoyable and loved by astronomers and those interested in astronomy and space sciences. To follow and photograph it.
The winter season begins tomorrow in Egypt and the countries of the northern hemisphere and will last about 88 days, 23 hours and 39 minutes. This day is the peak of winter astronomically and will be The shortest day of the year, as the length of the day is only about 10 hours, while the length of the night is approximately 14 hours. The sun also reaches its lowest height above the horizon at noon when it crosses the meridian, and the human shadow is on The Earth at this time is as tall as possible.
The winter solstice occurs in the northern hemisphere around December 21 or 22 of each year, when the sun reaches its lowest height during Noon is above the horizon, and the sun’s rays are strongly tilted over the northern hemisphere and almost perpendicular to the southern hemisphere, except for the Tropic of Capricorn, which is an annual astronomical event characterized by the sun’s perpendicularity over the Tropic of Capricorn.
