The Sloan Digital Sky Survey (SDSS), the largest multispectral imaging and spectroscopic redshift survey of the cosmos, has released its 20th data release (DR 20). It is also the third release of the survey’s fifth phase (SDSS-V), representing a massive operational expansion of the legacy established with prior releases. This milestone provides an unprecedented look at the stars, the interstellar medium (ISM) and distant galaxies that make up the cosmos.
