Story summary

The Dark Energy Survey improves understanding of dark energy, which constitutes nearly 70% of the universe.
DES analyzed data from 669 million galaxies over six years and found that both lambda-CDM and wCDM fit the observations.
Discrepancies in galaxy clustering patterns suggest further investigation is needed.
The DES team will refine models with data from the Vera C. Rubin Observatory in Chile to deepen insight into the universe's accelerating expansion and dark energy.
