An unusual planetary grouping begins tomorrow night and lasts for a week or so. Very low in the west-northwest at about 9:05 p.m., three planets dance above the horizon. On May 26, bright Venus lies at the lower corner of an equilateral triangle. Jupiter, recently a bright object in the west, has sunk so that it now sits just to Venus' upper left. Dim Mercury occupies the final point of the triangle to the upper right of Venus. Binoculars may be needed to find Mercury's feeble light in the bright twilight.
As the nights pass, Jupiter drops from view until late July, while Mercury rises higher above Venus.
Such is our view from Earth...
