New 3D Map of Universe Could Solve Dark Energy Mystery
The survey captured 47 million galaxies and quasars, giving researchers a new dataset to test dark energy and galaxy evolution models.
- On Tuesday, the Dark Energy Spectroscopic Instrument completed its five-year mission at Kitt Peak National Observatory in Arizona, creating the largest 3D map of the cosmos ever constructed.
- Originally designed to observe 34 million galaxies, the Nicholas U. Mayall 4-meter Telescope exceeded expectations by capturing 47 million galaxies and quasars plus 20 million stars since May 2021.
- Covering 14,000 square degrees, the dataset provides six times as many galaxies and quasars as all previous measurements combined, enabling investigation of dark energy, which constitutes about 70 per cent of the universe.
- Early DESI data suggested dark energy is weakening over time, noted Nathalie Palanque-Delabrouille, a Berkeley Lab scientist, challenging the standard cosmological model of constant cosmic acceleration.
- Operations will continue under DESI-II until about 2028, with the team revisiting unexplored sky regions while searching for dark matter, dwarf galaxies, and stellar streams.

A new map shows that the Universe behaves quite differently than the renowned physicist predicted. An international team of scientists has completed the largest 3D map of the Universe ever created. Data from the DESI instrument covers more than 47 million galaxies and suggests that dark energy, the cosmos's greatest mystery, may be unstable. This was reported by RBC-Ukraine, citing the Berkeley Lab. More interesting: "Space Pearl Harbor": The US…
It contains forty-seven million galaxies and quasars and could help solve the mystery of the weakening of dark energy.
