Abstract

SPHEREx, a modest space telescope with a mirror the size of a dinner plate, is set to launch into low-Earth orbit to map 450 million galaxies and create a 3D map of the universe. Costing less than 1/20 of NASA's JWST observatory, SPHEREx aims to search for evidence of cosmic "inflation" after the Big Bang, shedding light on galaxy evolution and the chemistry of our Galaxy. By analyzing the distances between galaxies and studying the evolution of galaxies, SPHEREx hopes to narrow down the possible drivers of inflation and understand the slowdown of star formation in galaxies.
