Workers study Hubble's main,eight-foot (2.4 m) mirror. When light enters Hubble,it reflects off the main mirror and strikes a second,smaller mirror. The light bounces back again,this time through a two-foot (0.6 m) hole in the center of the main mirror,beyond which Hubble's science instruments wait to capture it. In this photo,the hole is covered up | |
