Two billion years after the cosmos banged into existence, a mysterious force known as dark energy began shoving space outward ...

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.

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 ...

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 ...

Every single tiny point on the map is a galaxy.

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 25 years of planning, six years of data collection, and six more years of analysis, scientists have published a portion of the final results of the Dark Energy Survey (DES) — the largest, most ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

In a significant milestone, the Dark Energy Spectroscopic I (DESI) has completed its 3D map of the Universe—the highest ...

We may have seen the first hints of strange stars powered by dark matter. These so-called dark stars could explain several of the most mysterious objects in the universe, while also giving us hints ...

A small, seemingly technical assumption baked into the way astronomers standardize Type Ia supernovae may be responsible for the growing tension between different measurements of dark energy. New data ...
