If you saw two bright stars in proximity above Wednesday’s crescent moonset in the western New Mexico horizon, just wait until Monday, Dec. 21.
Those weren’t actually stars, but planets.
Jupiter and Saturn will continue to appear closer together until they reach a great conjunction, in which they resemble one big star. This hasn’t happened since 1623, and hasn’t been readily visible since the 1200s.
Some scientists have theorized it was this type of conjunction that was referred to in the Bible at the birth of Jesus. That’s why it has earned the nickname “Bethlehem Star.”
Watch the next few nights as they get closer and, barring too many clouds, see the big show Monday.
