When Dr. Leisa Townsley passed away this summer, the scientific community lost a brilliant researcher, teacher, and mentor. She was all of those things, but we wanted to feature some of the pivotal and critical ways that she helped the Chandra X-ray Observatory, specifically our Communications and Public Engagement work.
Chandra was launched into space in 1999 and with the beginning of its successful operations, a new era in high-energy astrophysics was born. For certain deep space objects that emitted enough X-ray photons, Chandra brought, for the first time, the ability to create richly detailed, high-resolution images. These X-ray images, however, were different in many ways from the images of its previously-launched sister Great Observatory, the Hubble Space Telescope.
Establishing a visual identity for Chandra, both on its own and in collaboration with other telescopes that study different kinds of light, including Hubble, was no small challenge. Our Chandra group was responsible for finding the best way to show X-ray data, which often looks completely different from optical data. Would traditional techniques used for visible light data be suitable to process X-ray data? Would new processes and tactics need to be developed to make X-ray data more accessible, easier to understand and process?
