Understanding Our Universe

Sun Kwok is a world-renowned astronomer who has revolutionized our understanding of stellar evolution and astrochemistry. Currently serving as Chair Professor of Space Science and Director of Laboratory for Space Research at the University of Hong Kong, he previously held the position of Dean of Science and Chair Professor of Physics (2006-2016). His groundbreaking 1978 theory on planetary nebulae formation transformed our understanding of how Sun-like stars die. After completing his education at McMaster University and earning his Ph.D. from the University of Minnesota-Twin Cities, he made significant discoveries including proto-planetary nebulae and a unique 21-micrometer emission feature. His research using space-based infrared telescopes demonstrated how organic compounds with aromatic and aliphatic structures could be rapidly synthesized during late stages of stellar evolution. As President of the International Astronomical Union Commission of Astrobiology and a Fellow of the American Association for the Advancement of Science, Kwok has published extensively on interstellar medium, planetary nebulae, and organic matter in the Universe. His influential books include "The Origin and Evolution of Planetary Nebulae," "Cosmic Butterflies," and "Stardust: The Cosmic Seeds of Life," which have contributed significantly to our understanding of space science and stellar evolution.
