May Skywatch

The best time to see Mercury is on the 6th, at about 35 minutes after sunset, when the charbroiled planet floats next to the crescent Moon, 12 degrees high in the west. Although Mercury remains visible until the 26th, it is only one-tenth as bright by then, at magnitude 2.0, and hidden by the twilight. Mars, halfway up the western sky at nightfall, crosses into Cancer and floats in front of the famous Beehive star cluster from the 22nd to the 24th. This fine sight is best viewed through binoculars. Saturn is highest at nightfall and appears above the Moon on the 12th. Jupiter, at magnitude -2.5, rises by midnight at month's end. Venus is too close to the Sun to be seen.
