DESI Legacy Imaging Surveys release 5.6-trillion-pixel 2D map covering three-quarters of the sky
↗
Astronomers have published the largest 2D map of the universe, combining 263,000 telescope exposures into a 5.6-trillion-pixel dataset spanning visible and near-infrared wavelengths.
This map provides a foundational reference for astronomical research, enabling engineers and scientists to cross-reference celestial objects with a high-resolution, multi-wavelength dataset. Its scale and accessibility may accelerate discoveries in cosmology and astrophysics, though processing such large datasets will demand significant computational resources.

The map aggregates 13 years of observations into 5.6 trillion pixels, covering nearly 4 billion celestial objects.
Data spans visible and near-infrared wavelengths, offering a multi-spectral view of three-quarters of the sky.
The release is integrated into the Legacy Imaging Viewer, a tool now routinely used in astronomy research.
