March 6, 2012, 45 minutes after sunset
Have you noticed those two bright “stars” forming a striking pair in the early evening western sky? They’re actually planets—Venus and Jupiter. They are so bright that you can spot them easily soon after sunset, before the sky is completely dark. Venus is the brighter of the two and currently lies to the lower right of Jupiter.
Over the next week watch Venus and Jupiter appear to creep closer and pass each other. Expect a particularly spectacular pairing the nights of March 12-14, 2012, when these two planets are at their closest all month (3° apart, or just a bit more than the width of your thumb when held at arm’s length).
March 12, 2012, 45 minutes after sunset
Although Venus and Jupiter are the most noticeable planets right now, they have company. Currently, Mercury also appears in the west, but will be trickier to spot. If you can find a good western horizon (no trees or buildings), you may catch this elusive planet as it sets in the evening twilight. About 45 minutes after sunset, try looking for Mercury far below and a little to the right of Venus. Although the last several days or so have been the best time this year for seeing Mercury in the evening, don’t wait any longer—Mercury’s light fades rapidly over the next week.
Turn around and look to the east for a bonus. By sunset, Mars has already risen in the east, in the direction of the constellation Leo. Currently, Saturn rises in the east about three hours after sunset, in the constellation Virgo. By the end of this month Saturn will rise just an hour after sunset.
To learn more about the planets and stars visible this spring, please join us for one of Morehead’s “Spring Skies” programs. The program designed for adults (interested teens are welcome) happens Wednesday evening, March 21, 2012. The version designed for families with children ages 7-12 is Saturday morning, April 14, 2012.
On Saturday, March 24, the crescent Moon joins Venus and Jupiter in the same part of the sky—a lovely sight! From 8-10 p.m. that evening, Morehead will host a free skywatching session at Jordan Lake (weather permitting).
