Summer News: An Award and an APOD

We recently learned that Dr Mike Lesser, Director of the Imaging Technology Laboratory of Steward Observatory, has won the 2022 Joesph Weber Award of the AAS. Dr Lesser is cited for “innovative and foundational work on methods of thinning, coating, and reading out large-format back-side illuminated CCD detectors. This work has led to significant improvements in performance, and the methods are used by virtually all CCD detectors in astronomical instruments working from optical through X-ray wavelengths.”
