On Monday, Las Vegas, along with the nation and the world, experienced an astronomical event that had not been seen since the merging of Jupiter and Saturn in the night sky on Monday and was closer together than since Galileo’s time in the 17th century.
It is the closest Jupiter-Saturn pairing since July 1623, when the two planets appeared a little closer.
Astronomers say that so-called conjunctions between the two largest planets in our solar system are not particularly rare. Jupiter passes its neighbor Saturn every 20 years in their respective laps around the sun.
But the one that appears is particularly close: Jupiter and Saturn are only a tenth of a degree from our perspective, or about a fifth the width of a full moon. They should be easily visible around the world shortly after sunset, weather permitting.
