There's something in the news today, I have read that over the weekend a seemingly rare event has occurred. It is called a "triple conjunction" which means that three celestial bodies appear near each other in the sky. The picture above is of a similar event three years ago over ESO's Very Large Telescope, with the same three celestial bodies, Jupiter, Venus, and the moon. This weekend it happened again over Southern California, and it seems that a conjunction itself is not that rare. There are plenty that happen with various planets in our solar system, and there are various kinds such as a great conjunction which involve Jupiter and Saturn that come about every 20 years or so. Some so rare they haven't happened again in 50 years since the last one, which was a great conjunction that involved all five of the naked-eye planets (Mercury, Venus, Mars, Jupiter, and Saturn) plus the sun and moon.
This is the article I read, and Wikipedia has some good information about upcoming conjunctions if you would be interested in catching one.
