The planetary players in our southwestern sky have changed over the past month. Jupiter is now too close to the horizon in the bright evening twilight to be seen. Mercury still can be found low about 30 minutes after sunset. It drops below the horizon around 6:30.
Venus reaches is greatest angular distance from the sun on January 14. It is at its highest in the western sky this year when it is first spotted which, for careful skywatchers, is just before the sun drops below the horizon. As darkness falls, Venus glows brilliantly, often being confused for an approaching airplane, or even a UFO. From a dark location, Venus is so bright that it can cast a shadow!
Such is our view from Earth ...
