"My all-time favourite exhibit is near the entrance to the Sky Theater... you walk through a doorway... and suddenly you are 15 feet away from a shifting, kaleidoscopic, red supergiant.  All around you stretch millions of twinkling stars. You look down and see stars, stars, stars, and the sphere of the supergiant curving away from you far, far down in the infinity of space. This is as close to a real spacewalk as you'll probably get.   (Graham Troyer-Joy, 13, published in Chicago Parent, Nov.1999)
