On March 19, the Dark Energy Spectroscopic Instrument (DESI) collaboration shared its findings in multiple papers posted on arXiv and in a presentation at the American Physical Society's Global ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda Cold Dark Matter, or ΛCDM, it weaves together dark energy, dark matter, and ...

Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly powerful telescopes, its true nature is still unknown. Now, scientists involved ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

NEW YORK — Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. Astronomers know that the universe is being pushed apart ...

NEW YORK — Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance. The force is enormous — it makes up ...

The U.S. National Science Foundation Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab, beneath streaking star ...

Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance. The force is enormous — it makes up nearly 70% of ...

Scientists with the Dark Energy Spectroscopic Instrument (DESI), an international research collaboration, presented new evidence Wednesday that bolstered its recent finding that dark energy is not ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...
