A new astronomical map contains 5.6 trillion pixels and approximately 4 billion celestial objects, including stars, galaxies, black holes, and asteroids. [^1]

The data were gathered by the Dark Energy Camera, the Nicholas U. Mayall 4-meter Telescope, and the UA Bok 2.3-meter Telescope at the NSF Kitt Peak National Observatory and the University of Arizona's Steward Observatory, complemented by NASA's Wide-field Infrared Survey Explorer. [^4]

David Schlegel, a researcher at the Lawrence Berkeley National Laboratory and co-lead of the Legacy Surveys, stated that the data is now part of the fabric of astronomy research. [^2]
