The completion of the DESI survey has provided a detailed 3D map of the universe, revealing over 47 million galaxies and quasars.

#SomewhereDeepInTheNight "This is a map of the universe. The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory, Arizona, has finished its five-year survey. It observed more than 47 million galaxies and quasars and created a 3D map centered on the Earth. Today's featured image shows a thin slice of these data: the black gaps indicate where our Galaxy obscures distant objects. " https://apod.nasa.gov/apod/ap260423.html
