Dark energy and black holes are two of the most mysterious topics when it comes to space, but they might actually be linked.

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

Astronomers have unveiled a new catalog of massive galaxy clusters, revealing new insight on the evolution of the universe ...

Most of our universe is hidden in plain sight. Though we can’t see or touch it, most astronomers say the majority of the cosmos consists of dark matter and dark energy. But what is this mysterious, ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

For over a decade, a dim but persistent glow near the center of the Milky Way has confused astronomers. This mysterious ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

An artist’s concept of the dark energy-driven accelerating expansion of the universe. New results suggest dark energy’s influence on cosmic expansion has weakened over time. In 2024 a shockwave ...

Dark energy makes up about 70% of the universe and causes its expansion to accelerate. It's different from dark matter; dark energy pushes space apart, while dark matter pulls things together. We ...

According to the model, dark matter may have started as particles that were hot, light, massless, and fast. As the universe cooled, these particles became heavy, slow, and dark, becoming an invisible ...

One of those ground-based telescopes is the Rubin Observatory, named after famed astronomer Vera Rubin. Unlike other ...

“Dark energy” is a term scientists use to refer to whatever is causing the universe to expand faster over time. We don’t know exactly what dark energy is—no one has ever directly seen or measured ...
