On December 21 was a sidereal show, three events coincided between dusk on Friday and early morning on Saturday.
The first was really the scenario in which the other two occurred. On Friday, the solstice was recorded, which produces opposing phenomena in each hemisphere.
Thus, in the northern hemisphere, it is the shortest day of the year and therefore the longest night of the year. There it is called the winter solstice.
While in the southern hemisphere, on the other hand, it is the longest day and the shortest night of the year, and is called the summer solstice.
The solstice occurs due to the inclined way in which the Earth revolves around the sun. Thus, the amount of light received by each part of the Earth is different throughout the year. The solstice marks the two moments, June and December, when the Earth reaches its greatest inclination toward the sun.
After the winter solstice in the northern hemisphere, the days begin to be gradually longer, which is why many cultures celebrate it as a stage of rebirth.
The cold moon
At dusk, the full moon was observed, the first of December and the last of 2018.
This moon is called the "cold moon" because it marks the arrival of winter in the northern hemisphere, and as it happens near the solstice it is also called long night moon, as explained by NASA.
This special night of full moon also counted on the meteor shower, which occurs annually.
According to geologist Trevor It was born in Forbes magazine, this rain started on December 17 and will last until 24.
