SDSS-V is the first facility providing multi-epoch optical & IR spectroscopy
across the entire sky, as well as offering contiguous integral-field
spectroscopic coverage of the Milky Way and Local Volume galaxies. This panoptic
spectroscopic survey continues the strong SDSS legacy of innovative data and
collaboration infrastructure.

Our latest data release, DR18 is now live! This is the first data release for
SDSS-V and contains targeting data for Black Hole Mapper and Milky Way Mapper,
as well as eFEDS spectra and value added catalogs. Find out more about DR18 on
the DR18 webpages, and in the DR18 paper.

If you are looking for previous data releases from SDSS-IV, then these are all
still available! You can find them on our completed surveys page, and at the
SDSS-IV webpages. Completed surveys include the SDSS Imaging and Legacy Survey,
Supernova Survey, SEGUE1/2, MARVELS, (e)BOSS, APOGEE-1/2, MaNGA and MaStar.

Our next data release will be DR19, and is currently scheduled for 2024.

 * ASTRONOMERS FIND QUASAR WINDS SPEEDING UP
   
   June 11, 2024
    
   A team of astronomers from the Sloan Digital Sky Survey has used eight years
   of careful, constant observations to discover unexpected changes in the winds
   surrounding a black hole.


 * THE “BARBENHEIMER STAR”: EVIDENCE FOR SPECTACULAR NUCLEOSYNTHESIS IN THE
   EARLY UNIVERSE
   
   January 10, 2024
   
   Astronomy’s new blockbuster is now playing in New Orleans. Astronomers from
   the Sloan Digital Sky Survey (SDSS) have discovered evidence for what they
   call the “Barbenheimer Star” – an enormous ancient star that exploded in a
   way previously thought impossible, resulting in an unusual pattern of
   elemental ashes that left behind a trail of evidence still visible billions
   of years later.


 * MAPPING EVERYTHING EVERYWHERE ALL AT ONCE
   
   August 2, 2023
   
   The newest mapmaking effort of the long-running Sloan Digital Sky Survey has
   begun. The Local Volume Mapper (LVM) Instrument has seen first science light.


 * SDSS-V'S ROBOTS TURN THEIR EYES TO THE SKY
   
   January 11, 2022
   
   After twenty-one years of observers loading heavy aluminum plates night after
   night, the Sloan Digital Sky Survey (SDSS) is now seeing the cosmos through
   robotic eyes. Following more than five years of design, development and
   construction, survey members worked over the final months of 2021 to install
   the new robotic Focal Plane System (FPS) on the Sloan Foundation 2.5m
   Telescope at Apache Point Observatory (APO).


 * SERVING UP THE UNIVERSE ON A PLATE
   
   July 13, 2021
   
   They may not look like much — just metal disks 80 centimeters (30 inches)
   across with some etched markings and hundreds of small holes — but round
   aluminum “plates” like this one from the Sloan Digital Sky Survey (SDSS) have
   been vital to mapping our universe for more than 20 years.


 * NEXT-GEN ASTRONOMICAL SURVEY MAKES ITS FIRST OBSERVATIONS TOWARD A NEW
   UNDERSTANDING OF THE COSMOS
   
   November 2, 2020
   
   The Sloan Digital Sky Survey’s fifth generation collected its very first
   observations of the cosmos at 1:47 a.m. on October 24, 2020. As the world’s
   first all-sky time-domain spectroscopic survey, SDSS-V will provide
   groundbreaking insight into the formation and evolution of galaxies—like like
   our own Milky Way—and of the supermassive black holes that lurk at their
   centers.

JOIN US!

SDSS-V, like previous SDSS surveys, remains committed to making its data
publicly available in a format that is helpful to a broad range of users, from
beginner students to both amateur and professional astronomers. However, without
extensive federal or other large-scale funding, this commitment is not possible
to fulfill without membership contributions from institutional partners. SDSS-V
is actively seeking participation from new membership partners. Our
institutional partners benefit from early access to proprietary data,
participation in the survey planning process, and involvement of their faculty,
postdocs, and students in our global science collaborative network.

Policies for joining SDSS-V at a variety of levels can be found in the Joining
Document. The general policies for SDSS-V are defined in its current Principles
of Operation.

A list of current member institutions can be found on the Affiliate Institutions
page.
