Astronomers drop one of the largest-ever maps of the universe, charting 4 billion objects

A deep space image showing a series of swirling galaxies in the darkness of space.

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 is so big, in fact, that it’s impossible to reproduce as a single image here; instead, astronomers invite you to explore their vision of the universe using the free Legacy Survey Sky Browser webpage.
