Astronomers release 5.6‑trillion‑pixel map covering 75% of sky

A collaborative team of astronomers has unveiled an unprecedented celestial map that captures roughly three‑quarters of the observable sky with a resolution of 5.6 trillion pixels. The image, compiled from data gathered by multiple ground‑based and space‑borne observatories, represents one of the most detailed surveys ever produced, encompassing an area equivalent to 75 percent of the sky’s total expanse.

The high‑definition map catalogs approximately four billion distinct celestial objects, ranging from nearby stars and distant galaxies to transient phenomena such as supernovae. Researchers anticipate that the extensive dataset will support a wide array of scientific investigations, including studies of cosmic structure, dark matter distribution, and the evolution of galaxies over billions of years. By providing an exhaustive visual reference, the map is expected to serve as a foundational resource for both current and future astronomical research.
