The Great Conjunction of 2020
December 21 was the winter solstice. In the Northern Hemisphere, it is the day with the longest night. This day also marked the Great Conjunction of Jupiter and Saturn. The last time these two planets were this close together was in Galileo's time in 1623. But that conjunction occurred in the daytime, so he never had the chance to view it. And before that, the previous great conjunction occurred in March 1226, when Genghis Khan was conquering Asia.
How amazing to witness such history in the unfolding story of the universe.
