Sloan Digital Sky Survey News

The Sloan Digital Sky Survey (SDSS) is a major astronomical survey that has been one of the most ambitious and influential mapping projects in the field of astronomy. Initiated in 2000, the SDSS uses a dedicated 2.5-meter telescope located at the Apache Point Observatory in New Mexico, USA. The survey’s main objective is to map a large portion of the sky in unprecedented detail, collecting data on millions of objects, including stars, galaxies, and quasars. Over its various phases, the SDSS has produced a comprehensive three-dimensional map of the universe, allowing scientists to understand the large-scale structure of the cosmos. It has contributed significantly to research areas such as dark matter, dark energy, and the large-scale structure of the universe. The survey utilizes state-of-the-art spectroscopic and imaging techniques to measure distances to galaxies and quasars, making it an invaluable resource for both professional astronomers and educational institutions worldwide.
