The James Webb Space Telescope: Promises Delivered

by Dr. Gregory Wirth



Online Zoom Invite also will be emailed.


Why was a "magic metal" key to designing the powerful new James Webb Space Telescope? How did scientists focus the optics after launch? And what amazing discoveries are astronomers making now that Webb is fully operational and returning fantastic new images to us almost daily? In this presentation, hear local expert Greg Wirth explain how engineers designed Webb's mirrors, what was involved in turning 18 separate mirror segments into a single telescope, and what scientists are learning from the data.


Dr. Gregory Wirth is an astronomer and systems engineer at Boulder-based Ball Aerospace.  Since clear nights were a rarity growing up in cloudy and light-polluted central Michigan, Greg was blown away the first time he saw the night skies in Colorado as a teen.  He earned his Ph.D. in Astronomy & Astrophysics at the University of California, Santa Cruz and spent sixteen years as a Support Astronomer at the W. M. Keck Observatory on Mauna Kea in Hawaii. Prior to joining Ball in 2018, Greg served as the Commissioning Scientist for the Boulder-based National Ecological Observatory Network.  At Ball, he has supported the Roman Space Telescope program and spent last winter commuting from Boulder to Baltimore as a member of the Wavefront Science Team responsible for commissioning the optical systems on the James Webb Space Telescope.  He lives in Longmont and plans his bike rides around the best snack stops.
