This page shows our official press releases announcing discoveries during the current fifth phase of the SDSS. For more discoveries, see the press releases of the previous generations of the SDSS, listed at the bottom of this page.
The Sloan Digital Sky Survey (SDSS) has officially launched its twentieth data release (DR20), marking the third data release for the fifth phase of the survey (SDSS-V). DR20 represents a massive operational expansion of the foundations laid in prior releases.
The Black Hole Mapper reaches a milestone with its first southern hemisphere optical observations, coordinated eROSITA X-ray identification, and multi-epoch tracking of accreting black holes across the universe.
LAS CAMPANAS OBSERVATORY, CHILE — While the Milky Way appears from Earth as a serene, glowing band stretching across the night sky, zoom in closely and a picture of dynamic cosmic mayhem emerges. Galaxies are living, evolving ecosystems driven by the lifecycles of their stars. Massive stars are born in cold molecular clouds, live short, […]
The Sloan Digital Sky Survey V (SDSS-V) has announced its twentieth public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled of stars in and around our home galaxy.
A class of undergraduate students at University of Chicago has used data from the Sloan Digital Sky Survey (SDSS) to discover one of the oldest stars in the universe, a star that formed in a companion galaxy and migrated to the Milky Way. The ten students found the star as part of their “Field Course […]

Astronomers have discovered that many small galaxies hosting active supermassive black holes have their stars and gas spinning out of sync – sometimes in completely opposite directions.
A new study from the Sloan Digital Sky Survey has revealed a surprising truth about black holes: they spin faster than previously thought, revealing a more orderly early universe than we ever suspected.
The Sloan Digital Sky Survey (SDSS) is embarking on its most innovative spectroscopic survey yet of our Milky Way: creating a comprehensive map of the interstellar material in our Galaxy.
A student-led team has observed that the mass-radius relation of white dwarf stars, a type of star which is so dense that they are supported by quantum mechanical effects, depends on the temperature of the star. Scientists have long searched for this subtle effect, detected here for the first time using a method from General Relativity – along with the largest catalog of white dwarf data of its kind.

A team of astronomers from the Sloan Digital Sky Survey (SDSS) has used eight years of careful, constant observations to discover unexpected changes in the winds surrounding a distant black hole.
