Three bright planets - Jupiter, Venus, Saturn - can still be found in the west after sunset. Day by day, Venus will climb upward while Jupiter and Saturn sink toward the sunset glare. Venus and Saturn will meet up for a conjunction on December 10. In the morning sky, as the month begins, keep watching for Mercury and Mars. They rise in the east before the sun. Read more.

What a week it's been for planets! Jupiter and Venus - the 2 brightest planets - were in conjunction last Sunday. Then the moon swept through the evening sky, passing Jupiter, Venus and Saturn. The sky scene on November 28 - Thanksgiving evening for us in the U.S. - was particularly striking. This one is the Southern Hemisphere view, from Peter Lowenstein in Mutare, Zimbabwe. Venus and Jupiter are near the moon, Saturn in the photo's top right. Our special thanks to all in the EarthSky Community who contributed photos. More photos here.
