Terry Herter's interests include normal and starburst galaxies, circumstellar disks, and the galactic center. In the recent past he has also studied HII (ionized hydrogen) regions and planetary nebulae. From time to time, he has dabbled in planetary astronomy: observing planets, moons, and comets. Recent work has included the study of the formation of massive stars and their interaction with their environments, and exploration of the very center of our Galaxy where three large star clusters exist. He has also worked on the development and testing of infrared arrays for ground-based, airborne, and space-based astronomy.
