5.6-Trillion-Pixel Map of Universe Is Biggest Ever Made
The public survey combines 263,407 exposures and may aid searches for dark matter, supernovae and gravitational lenses, researchers said.
- Astronomers have released the largest-ever 2D map of the universe, charting nearly 4 billion objects across roughly 75 per cent of the sky in visible and near-infrared light.
- A team of over 160 scientists created the 5.6 trillion-pixel map by combining 263,407 telescope exposures collected over 13 years, establishing the 2D foundation for DESI's 3D mapping efforts.
- Publicly available through the Legacy Survey Sky Viewer, the dataset enables researchers to hunt for gravitational lenses and dark matter, building on earlier versions cited in more than 1,800 scientific papers.
- "It's part of the fabric of astronomy research now," said David Schlegel, co-lead of the Legacy Surveys at Lawrence Berkeley National Laboratory, noting astronomers routinely use the viewer to identify objects.
- The underlying DESI project continues mapping 3D structures to trace dark energy across the universe, while scientists expect this comprehensive 2D portrait to remain the most detailed sky survey for years.

Astronomers created the largest-ever 2D map of the universe, charting 4 billion objects in the night sky
The largest 2D map of the universe just dropped, and it’s a stunner. Compiled from more than a decade of observations, the new map charts 4 billion stars, galaxies, black holes, asteroids and other objects of interest throughout the cosmos. The map reveals about three-quarters of the night sky in high resolution, spanning both visible and near-infrared light wavelengths and charting the areas of the universe not blocked by dust or gas. The map i…
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 vi…
