Using the Cerro Tololo Inter-American Observatory (CTIO), an international team of astronomers have performed deep optical observations of a dwarf galaxy known as NGC 300. As a result, they detected a ...

We don't know what it is yet, so in the same spirit we dubbed it dark energy. All of this comes together, along with ordinary matter, to form what we call the lambda cold dark matter (ΛCDM) model. The ...

New research suggests dark energy might not be real, proposing instead that the Universe’s apparent acceleration is due to its patchy structure. Upcoming observations from space missions could prove ...

NSF NOIRLab rings in the New Year with a glittering galaxyscape captured with the Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M.

"ingredient," dark energy, since its discovery almost three decades ago. This was the first year that scientists got an exciting observational hint that the force driving the accelerating expansion of ...

It also raised the question of what was causing this acceleration. Cosmologists eventually decided that the expansion was being driven by a force they called dark energy and began to develop a ...

Russian missile and drone attacks are continuing across Ukraine as the country already faces a cold, dark winter after Russia’s strikes destroyed about half of the country’s energy infrastructure.

As Puerto Ricans welcomed 2025, many faced the grim-reality of celebrating in the dark as outages lingered ... operating the power plants, and LUMA Energy, the Canadian-American company ...

has become a source of frustration to government ministers and a potential pitfall on their journey to cleaner energy. A German term that translates to “dark doldrums,” Dunkelflaute refers to ...

The enigmatic idea of dark energy has consistently been referenced to explain the universe’s expansion, but new research may upend years of cosmological beliefs with a shocking claim made by ...

Scientists challenge the existence of dark energy. They suggest the universe's accelerating expansion is due to uneven gravitational effects on time. This new theory, called the "timescape" model ...
