http://spaceweather.com/The long-awaited sunset sky show of May 2013 is beginning. In only a few days, Venus, Jupiter and Mercury will form a tight triangle in the western sky, visible to the unaided eye around the world. Last night, Fred Espenak of Portal, Arizona, photographed the trio in the early stages of convergence:
"The three planets were easily visible to the naked eye in spite of the bright twilight glow," says Espanel. "Mercury should be even easier to spot in the coming days as it climbs higher into the sky. "
In the nights ahead, the line of planets will collapse to form a triangle. At closest approach on May 26th, they will fit within a circle less than 3o wide. Start watching tonight--it's a great way to end the day
