Scientists create largest 2D map of the universe with 5.6 trillion pixels and nearly 4 billion cosmic objects

Astronomers have released the largest two-dimensional map of the universe ever created, offering a sweeping new view of nearly 4 billion celestial objects across roughly three-quarters of the sky.

The new map, created by the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys team, contains a staggering 5.6 trillion pixels and combines more than 263,000 telescope exposures collected over more than a decade. The observations span visible and near-infrared wavelengths, providing an enormous portrait of stars, galaxies and other cosmic phenomena across the sky, according to a statement from the National Science Foundation (NSF) NOIRLab.

"It's part of the fabric of astronomy research now," David Schlegel, co-lead of the Legacy Surveys and a scientist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, said in Read Entire Article
