Awbury Arboretum on Friday night, April 26,2013 was one of many venues set up throughout the city for stargazing as part of the 10 day Philadelphia Science Festival. A few dozen or so people showed  up at the Arboretum in Germantown. Teenager  Maya Anderson came to just hang out with her family and, as a choir student at Settlement Music School,  sang impromptu from some of her repertoire.    Katie Virtue, a meteorologist and volunteer with the Franklin Institute was on hand to guide visitors to the celestial sights. Some astronomy enthusiasts brought powerful telescopes and lines formed at these for viewing the four moons of Jupiter on this clear, cool spring night.  Video story here. And here is Maya "Piping down the valleys wild" from Songs of Innocence by William Blake.
