Mapping the cosmos with a 570-megapixel lens

Exploring 7 billion light years of space with the Dark Energy Survey · 7:22 · Video: Fermilab · Watch at the source

In short: The Dark Energy Survey is capturing the largest maps ever created of our universe's galaxy distribution. This video explains how scientists use high-resolution imaging to decode the evolution of space and the mysterious roles played by dark matter and energy.

By photographing galaxies both nearby and billions of light years away, the survey provides a massive test for current cosmological predictions. The analysis of the first three years of data has allowed researchers to visualize how matter is distributed across the cosmos.

This work addresses fundamental questions regarding the universe's composition and evolution. It specifically seeks to understand what the universe is made of and how dark energy and dark matter influence its structure over time.
