Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term ...

NASA’s Nancy Grace Roman Space Telescope will conduct a wide-area survey to study dark matter, dark energy, and the expansion of the universe across 11 billion light-years.

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

The deepest mysteries of the universe often begin with the biggest questions. Few are more puzzling than the birth of supermassive black holes. These giants, weighing millions to billions of times ...

A doctoral researcher in Australia has successfully recreated cosmic dust inside a laboratory, offering a new way to study ...

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 ...
