The Sloan Digital Sky Survey V has taken a major step toward mapping the sky on a truly global scale with Data Release 20. Known as DR20, the release includes the first optical (BOSS) SDSS-V spectra collected from the Southern Hemisphere, greatly expanding the survey beyond the groundwork established in earlier releases.
By combining these new southern observations with data gathered in the north, SDSS-V is bringing panoptic spectroscopy across both hemispheres. The result gives astronomers a broader view of stars, interstellar gas, and distant galaxies throughout the cosmos. DR20 contains part of the much larger panoptic spectroscopic map that the ongoing SDSS-V survey is continuing to build.
Studying both the nearby and distant Universe is essential for understanding the physical processes that shape it. DR20 advances that effort while moving SDSS-V further into an era of multi-wavelength, multi-epoch optical and infrared observations.
What Is New in Data Release 20?
DR20 includes a wide range of resources for researchers and astronomy enthusiasts. Among them are catalogs covering black holes, stars, and interstellar gas, along with new visualizations and scientific tools designed to help users explore the enormous dataset.
