Dilhan Eryurt was a Turkish astrophysicist who made significant contributions to scientific research on space. Born on November 29, 1926, in Izmir, Türkiye, Eryurt spent her childhood in various cities due to her father’s career. She began her education at Beşiktaş High School, where she discovered her early interest in mathematics. This passion eventually became her professional career when she pursued a bachelor’s degree at Ankara University’s Faculty of Science, majoring in Mathematics and Astronomy. After graduating, Eryurt deepened her interest in astronomy and, in 1953, completed her master’s degree in astrophysics at Istanbul University, becoming one of Türkiye's pioneering figures in the field.

Scientific Career and NASA Contributions

In 1956, Eryurt received a grant from the International Atomic Energy Agency and went to Canada, later continuing her research at the University of Michigan in the United States. The pivotal moment in her scientific career came in 1961, when she began working at NASA's Goddard Space Flight Center. During this time, Eryurt made significant contributions to astrophysics through her work on solar evolution and stellar models. While at NASA, she played a critical role in the planning of the Apollo lunar landing projects. In particular, her studies of the Sun's energy output and the radiative properties of stars informed the development of equipment used in the Apollo programme. Her remarkable contributions earned her the Apollo Achievement Award in 1969, a milestone that cemented her place in the scientific community.

Return to Türkiye and Academic Contributions

In 1973, Eryurt returned to Turkey and joined the Department of Physics at the Middle East Technical University (METU). Under her leadership, astrophysics research in Turkey gained momentum. She spearheaded the establishment of the Department of Astrophysics at METU, which greatly enhanced Türkiye's reputation in the international scientific community. Eryurt also mentored many young scientists, leaving a lasting legacy. Throughout her academic career, she conducted research on the evolution of the Sun and stars, galaxy dynamics and cosmology. She published numerous articles and papers in the field of astrophysics and successfully represented Türkiye at various international scientific conferences.

Achievements and Legacy

Dilhan Eryurt’s scientific contributions were recognized nationally when she received the Scientific Service and Encouragement Award from the Scientific and Technological Research Council of Türkiye (TÜBİTAK). Her work has had a profound impact on science, both nationally and internationally, earning her recognition as the scientist who introduced Türkiye to the field of astrophysics.
