570-Megapixel Eye Maps the Cosmos, Tightening Dark Energy Clues

The Dark Energy Survey used the 570‑megapixel Dark Energy Camera on the Blanco telescope to combine weak lensing, galaxy clustering, BAO, Type Ia supernovae, and other probes over six years, delivering the clearest expansion history of the Universe to date and broadly supporting the standard Lambda-CDM model while noting a remaining tension, with the Rubin Observatory’s decade‑long Legacy Survey approaching.
