DAS 2023 Dinner Meeting
The 2023 Dinner Meeting was held at
St. Thomas Episcopal Church.

Our 2023 Guest Speaker was:Dr. Jonathan P. Gardner,Deputy Senior Project Scientist, James Webb Space TelescopePresenting:"Science with the James Webb Space Telescope" |

The James Webb Space Telescope was launched on Christmas Day 2021 after 25 years of planning, design, development, construction, and testing. Following a six-month deployment and commissioning period, the first science results from Webb have engaged the public and surprised the scientists. Webb’s science goals address our origins and the history of the universe: the first stars and galaxies that formed after the Big Band; the sizes, shapes, and components of galaxies as they evolve; the formation of stars and planetary systems; and exoplanets, the history of our own Solar System, and the conditions for life on other planets. In its first months of scientific operations, Webb has already found the most distant galaxies ever seen. The light from these galaxies has been traveling for 13.5 billion years of the 13.8 billion years since the Big Bang, allowing us to study early galaxies that formed under very different conditions than we see today. Webb has made the first detection of carbon dioxide in the atmosphere of an exoplanet and has examined the interactions between giant stars and the planets that are forming near them. I will review Webb’s construction, launch, and deployments, and discuss the commissioning of the telescope and its instruments. I will describe what we have learned in the first nine months of science results from the telescope and look ahead to additional results expected in the coming years.
Bio:
Jonathan P. Gardner is the Deputy Senior Project Scientist for the James Webb Space Telescope, a position he has held since 2002 at NASA’s Goddard Space Flight Center. The James Webb Space Telescope, the successor to the Hubble Space Telescope, looks backwards in time to find the first galaxies that formed after the Big Bang, to trace their evolution into galaxies like our own Milky Way, and to connect the formation of stars and planets with the history of our own Solar System. Gardner received an AB degree from Harvard and MS and PhD from the University of Hawaii. As a NATO Fellow, he did postdoctoral research at the University of Durham in the UK. He came to NASA-Goddard in 1996 to work with the Hubble Space Telescope, but soon got involved in early studies of Webb. His scientific research involves using deep infrared observations to study the statistical evolution of galaxies. On the Webb project, he works with the other scientists to ensure the scientific success of the mission, now coming to fruition with Webb’s early results. In addition to his role on Webb, Gardner also served as the Chief of Goddard’s Observational Cosmology Laboratory from 2006 until the launch of Webb on Christmas Day, 2021.
