The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. – Image credit: Dan Long (Apache Point Observatory)

Science Bulletins: Sloan Digital Sky Survey—Mapping the Universe
Taking a census of all the luminous objects in one-quarter of the visible cosmos is a hefty accounting job. It takes a specially-built telescope on task every clear night for eight years, wielding one of the biggest digital cameras on the planet. Over a hundred million stars, galaxies, and quasars have been tallied so far. Meet the astronomical observers and theorists set on divining the three-dimensional structure and origins of the Universe from these unprecedented scores of data.
A Flight Through the Universe, by the Sloan Digital Sky Survey
This animated flight through the universe was made by Miguel Aragon of Johns Hopkins University with Mark Subbarao of the Adler Planetarium and Alex Szalay of Johns Hopkins. There are close to 400,000 galaxies in the animation, with images of the actual galaxies in these positions (or in some cases their near cousins in type) derived from the Sloan Digital Sky Survey (SDSS) Data Release 7. Vast as this slice of the universe seems, its most distant reach is to redshift 0.1, corresponding to roughly 1.3 billion light years from Earth. SDSS Data Release 9 from the Baryon Oscillation Spectroscopic Survey (BOSS), led by Berkeley Lab scientists, includes spectroscopic data for well over half a million galaxies at redshifts up to 0.8 -- roughly 7 billion light years distant -- and over a hundred thousand quasars to redshift 3.0 and beyond.

The SDSS 3D Map of the Universe Flythrough
https://scitechdaily.com/largest-3d-map-of-the-universe-ever-created-astrophysicists-fill-in-11-billion-years-of-our-universes-expansion-history/ This video presents the most detailed 3-dimensional map of the universe known to humankind, the one obtained by the Sloan Digital Sky Survey. Scientists from around the world have just completed a 20-year-long survey of the night sky, measuring the positions and distances of more than 4 million galaxies and quasars. This detailed map will help scientists shed light on the remaining mysteries of our Universe. Let’s go on a journey from the local stars to the largest scales of our Universe! Credits: EPFL
The Wave in the Milky Way
This animation shows the results of a computer simulation of the warping of the Milky Way Galaxy, which arises from a wave of stars passing through
Simulation of the formation of the Milky Way
This movie shows a computer simulation of a galaxy like the Milky Way. The movie fast-forwards through simulated time from 13 billion years ago to today. The main galaxy grows as many small galaxies merge with it. Heracles resembles one of the smaller galaxies that merged with the Milky Way early in the process.

Sloan Digital Sky Survey Public Event, 26 June 2020
This is a recording of a virtual public outreach event that was hosted by members of the Sloan Digital Sky Survey (SDSS) on Friday, June 26th, 2020. In this 1.5 hour video, you will learn about the SDSS's international effort to make the largest ever 3D map of the universe, get an exclusive tour of the machine shop where our iconic survey plates are drilled, and explore the universe for yourself in a live scavenger hunt through our vast imaging of the night sky! Useful time stamps:
- 1:30: Welcome and introduction of the astronomers
- 10:30: Intro to SDSS and to how astronomers collect data
- 29:45: Tour of the Plate Lab at the University of Washington
- 53:30: Plates for Education Program and how educators can request a plate of their own
- 55:00: How SDSS maps the sky, and the SkyServer scavenger hunt

Mita Tembe talks about APOGEE Instrumentation on SnapChat
A compilation of Snachat's from Mita Tembe (University of Virginia) about her work on SDSS-IV survey APOGEE. Mita began working on hardware for the APOGEE-2S spectrograph as an undergraduate at the University of Virginia and has been working full time for the project as a Lab Technician/Research Assistant since September 2015. The video includes a tour of the dome at Las Campanas, a high-level explanation of how the APOGEE instrument works, the installation of two optics, and Mita answering questions some students sent in.
Happy Retirement, Dan Long, from SDSS
A video tribute to Dan Long, Chief Engineer, Sloan Foundation Telescope, who will be retiring next year. A nice view of the history of SDSS and many of the people who work on the mountain at Apache Point Observatory. Music: Welcome to Nightvale soundtrack by Disparition.
