Visualization of the SPHEREx Galaxy Catalog

SPHEREx team members from Argonne National Laboratory have created an exciting new visualization of the galaxy catalog that SPHEREx will generate (if approved by NASA, that is). Specifically, the Argonne scientists created a fly-through movie demonstrating how SPHEREx will map out the extragalactic sky in three dimensions. Watch the video below to see how SPHEREx will reveal the large-scale structure of the universe (galaxy clusters and voids, visible in blue and black) by measuring the redshifts of nearly 500 million galaxies with a precision of 10%. But there's more -- SPHEREx will measure the redshifts of another 16 million galaxies with an exquisite 0.3% precision. More about the groundbreaking science this will enable.
