The world was treated to that sight on Monday night. But it was visible in clearer night skies from Los Angeles to the United Kingdom, giving us plenty of stellar photos to see the conjunction after the fact. NASA says the planets regularly appear to pass each other in the Solar System, with their alignment happening once every 20 years. However, this year was special because they haven’t passed this close to each other since the early 1600s. Furthermore, it had been about 800 years since the alignment occurred at night, allowing almost everyone on earth to witness the event.
