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 ...

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

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 ...

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 ...

Although dark matter is invisible, its various effects can still sometimes be seen—such as in this Hubble Space Telescope image of the galaxy cluster Abell 370 some four billion light-years from Earth ...

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

Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange glowing objects potentially ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...
