Did you see the three planets after sunset last night? Jupiter, Venus and Mercury formed a near-perfect equilateral triangle in the western twilight sky. Tonight – May 27, 2013 – the triangle is not so equal-sided, but you can still witness the planetary trio that pops out over the western horizon about 45 to 75 minutes after sunset. Don’t miss these three planets! You’ll be looking over the sunset point on the horizon at evening dusk. Be sure to find an unobstructed horizon in the direction of sunset, and if you have them, bring along binoculars to enhance the view of the three planets.
