Dr. H. Philip Stahl, senior optical physicist at NASA's Marshall Space Flight Center, will discuss the James Webb Space Telescope (JWST) at Samford University's Christenberry Planetarium on Tuesday, June 20, at 7 p.m. The public is invited free of charge.
The JWST, which replaces the Hubble telescope, will search for the first luminous objects of the universe to help answer questions about how the universe came to look as it does today. The telescope is scheduled to begin its 10-year mission in 2011.
At Marshall, Dr. Stahl is the JWST optical components technical lead. He is a leading authority in optical metrology, optical engineering and phase-measuring interferometry.
