Dark Energy Spectroscopic Instrument, Scientific spectrometer at Kitt Peak National Observatory, Arizona
The Dark Energy Spectroscopic Instrument is an advanced spectrometer located at Kitt Peak National Observatory in Arizona, equipped with 5000 optical fibers and ten spectrographs. These components work together to capture and analyze light from distant galaxies across the sky.
Construction of this spectrometer began in mid-2016 and achieved first light observations in October 2019 at Kitt Peak. Since then it has continuously mapped the universe, contributing to our understanding of cosmic expansion.
The facility brings together researchers and astronomers from around the world pursuing shared discoveries about the universe. This location embodies international cooperation in modern scientific inquiry.
The instrument operates at an elevation of 2100 meters and uses the Mayall Telescope for data collection. Visitors should be prepared for the mountainous setting and remember this is an active research center.
The instrument can collect data from up to 35 million galaxies while creating the largest three-dimensional map of the universe ever made. This enormous amount of information allows scientists to see the large-scale structures of the cosmos in completely new ways.
