The Nobel Prize in Physics 2019 was awarded to three astrophysicists for their "contributions to our understanding of the evolution of the universe andEarth's place in the cosmos". Half of the prize went to James Peebles for his "theoretical discoveries in physical cosmology". Most notably, these include his pioneering research in revealing the origin of the cosmic microwave background (CMB) in 1970's and in establishing the cold dark matter (CDM) model of the universe in 1980's, both of which have fundamentally shaped our current view of the universe. The other half of the prize was awarded jointly to Michel Mayor and Didier Queloz for their "discovery of an exoplanet orbiting a solar-type star" in 1995, which has opened up the window to the numerous "new worlds". To date, more than 4,000 extra-terrestrial planets have been found, and the study of exoplanets has become a new, the most fast-growing branch of astronomy. This year's Laureates have given us "new perspectives on our place in the universe". This talk is to present and to explain their research.
