Euclid Maps 900 Million Galaxies

ParisEuclid mapped 900 million galaxies in 13 months of observing.

The release totals 1.7 petabytes, a first test of how dark matter bends light.

Euclid measures galaxy distances, so scientists can rebuild the cosmic web, whose clusters and voids depend on dark energy and dark matter.

The release covers only 14% of the sky Euclid will survey over six years.

First dark energy and dark matter results come next year, and the full atlas is due in 2031.
