SPHEREx Will Explore the Origins of the Universe
SPHEREx will study the cosmic origins of the universe, galaxies and water in planetary systems. During its two-year mission, SPHEREx will survey the entire sky in optical and near-infrared light.
The data from SPHEREx’s survey will be used to study:
-
The nature of physics that drove cosmic inflation in the early universe;
-
The properties of interstellar ices, a key reservoir for water and biogenic material in the early phases of star and planet formation; and
-
The cosmic history of galaxy formation.
By surveying hundreds of millions of galaxies and stars, SPHEREx will help astronomers understand how our universe evolved while studying the abundance of the ingredients for life in our Milky Way galaxy’s planetary systems.
