| Science


The number of stars in the Universe is staggering. Because there are billions of stars in each galaxy and there are billions of galaxies, the total number is hard to comprehend. When astronomers at the Subaru Telescope think about this colossal number of stars, questions come to their minds that include, what is the population distribution of these stars in terms of the weight? How many stars are heavier or lighter than the Sun? What is the mass range of the stars formed in the Milky Way Galaxy?
