Year Name Image Motivation 2020 Lisa Kewley "For her fundamental contributions to our understanding of galaxy collisions, cosmic chemical abundances, galactic energetics, and the star-formation history of galaxies by elucidating key processes in star-forming galaxies, including nebular physics, accretion by supermassive black holes, and oxygen enrichment." 2018 Ewine van Dishoeck "A world leader in the fields of molecular astronomy and astrochemistry, van Dishoeck employs observations, theory and experiments to explain the evolutionary traits that lead to the formation of stars and planets from interstellar gas and dust, as well as the chemical basis for the origin of life."[2] 2016 Timothy M. Brown [Wikidata] "For his visionary scientific and technical advancements that have been critical to the fields of helioseismology, asteroseismology, and the emerging field of spectroscopy of transiting exoplanets, and for his critical role in helping a new generation of scientists and facilities to succeed." 2014 Robert Kirshner "For his work with students using supernova light curves as calibrated standard candles, providing evidence for an accelerating expansion of the universe.
