Fly through space with DESI
The Dark Energy Spectroscopic Instrument is making a 3D map of space to understand dark energy, the force behind the accelerating expansion of our universe. Part of DESI’s preparations included the “One-Percent Survey” visualized in this flythrough. Researchers took detailed images in 20 different directions on the sky, creating a 3D map of 700,000 objects and covering roughly 1% of the total volume DESI will study. With the instrument and survey plan successfully tested, the main DESI survey is now filling in the gaps between those observations.
