For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and faster forever. Now a wave of new measurements suggests that this invisible ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.

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 ...

Astronomers working with NASA’s James Webb Space Telescope have produced the sharpest wide-area map of dark matter ever assembled, more than doubling the resolution of previous efforts built on Hubble ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

After five years of mapping the sky in 3D — an area that stretches from Earth’s front porch to about 11 billion light-years away — researchers at the Dark Energy Spectroscopic Instrument (DESI) ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

But no one knows what dark energy actually is. One suggestion is that it might be a kind of energy associated with empty space known as the “ cosmological constant,” an idea first proposed by Albert ...

Quantum materials, astronomy, and life sciences research at UBC got a major boost with the latest round of Canada Foundation ...
