Today marks the 19th anniversary of the death of Marc Aaronson, an astronomer from the University of Arizona. Dr. Aaronson was killed in an accident while observing here at Kitt Peak.
This was a tremendous loss to astronomy. Dr. Aaronson was active in many areas of research, from the evolution of stars in our galaxy to the distance scale of the entire universe. He was a highly-motivated researcher who was very enthusiastic about his work.
While I never met Dr. Aaronson, his impact upon the people and science at Steward Observatory is still quite visible.
