Astronomers Unfurl Record 5.6 Trillion Pixel Map Of The Entire Cosmos
Scientists have released the largest 2D color map of the universe ever created, complete with a high-res view of nearly four billion celestial objects spanning three-quarters of the night sky.
Produced by the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys team, this digital map contains a staggering 5.6 trillion pixels and was thirteen years in the making. This cosmic portrait was compiled by combining 263,407 individual exposures gathered across 2,285 nights from three major sky surveys. Key contributing facilities include the National Science Foundation (NSF) Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory and the NSF Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, equipped with the Department of Energy's Dark Energy Camera (DECam).
By capturing the universe across visible and near-infrared light, the map avoids much of the dense gas and dust blocking views within our own Milky Way galaxy. Thus, the resulting atlas...
