Today is a special day, but not only because of the appearance of the phenomenon known colloquially, "Star of Bethlehem", it is also because today is the shortest day of the year, for all the people who live in the southern hemisphere.
The winter solstice is the result of the sun being positioned much further south, for this reason, the sunlight seems to last much longer while the night is shorter. In general, the position of the sun makes the whole day shorter.
Just as in the northern hemisphere it is the shortest day of the year, on the other hand, in the southern hemisphere it is the longest day. The winter solstice happens every year, with December 21 being the day it normally occurs. This phenomenon also marks the beginning of winter, which ends on March 20, 2021. This happens because the planet earth revolves around the sun and its own axis, while that axis must imagine which straight line that goes from the North Pole to the South Pole and is not perpendicular but rather has an angle of 23.5 degrees that will make that from March to September it leans towards the sun, which is what will mark the various seasons.
It should be noted that since ancient times, human civilization has been aware of these events called solstices, even they have even caused the development of rites and special celebrations in their names.
In addition, today it also happened that Saturn and Jupiter were aligned and this generated that, at first glance, it seems that they are only a celestial body. For this reason, this phenomenon is known as the 'Star of Bethlehem'.
