Findings from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy could be evolving over time. If they're right, cosmology will need a new model. When you purchase through links ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and ...

WASHINGTON (Reuters) - New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible ...

However, findings from the Dark Energy Spectroscopic Instrument (DESI) in March 2025 challenged this view. DESI was designed to track the acceleration of millions of galaxies and unravel the secrets ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

DESI, seen here beneath star trails, aims to create a 3D map of the universe. PNO / NOIRLab / NSF / AURA / B. Tafreshi Dark energy, a mysterious force that drives the accelerating expansion of the ...

Studies suggest that the universe's expansion is decelerating — but what could that mean for the future of the cosmos?

Dark energy, the mysterious force that makes up 70 percent of everything in existence, was hypothesized to explain why the expansion of the universe was accelerating. Ever since, it’s been thought of ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

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 ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...
