![]() ![]() Keivan Stassun, Stevenson Professor of Physics and Astronomy, is co-investigator of NASA TESS, which enabled the discovery of a newly formed exoplanet in June 2020. The SDSS-V will make full use of existing satellites, including NASA's Transiting Exoplanet Survey Satellite mission, to lead to new discoveries. The fifth generation of the Sloan Digital Sky Survey is collecting data about our universe for Vanderbilt University astronomers and other project members to use to explore the formation of distant galaxies and supermassive black holes, and to map the Milky Way.

The right panel shows the image and spectrum of a white dwarf –the left-behind core of a low-mass star (like the Sun) after the end of its life. The purple blob is an SDSS image of the light from this disk, which in this dataset spans about 1 arcsecond on the sky, or the width of a human hair as seen from about 21 meters (63 feet) away. The left panel shows the optical-light spectrum of a quasar–a supermassive black hole at the center of a distant galaxy, which is surrounded by a disk of hot, glowing gas. SDSS-V simultaneously observes 500 targets at a time within a circle of this size. The purple circle indicates the telescope’s field-of-view on the sky, with the full Moon shown as a size comparison. The central sky image is a single field of SDSS-V observations. This image shows a sampling of data from those first SDSS-V data. The Sloan Digital Sky Survey’s fifth generation made its first observations earlier this month.
