For years, three cosmic phenomena have puzzled astronomers. An ultradense concentration of matter distorts the light from a ...

The James Webb Space Telescope (JWST) has uncovered supermassive black holes when the Universe was barely 500 million years ...

A new kind of dark matter could help explain some of the universe’s mysteries, a new study suggests. The study proposes that there are dense clumps of “self-interacting dark matter”, or SIDM, each ...

Modern cosmology assumes dark matter exists. But what makes us so certain that dark matter is the answer—and what if we're wrong?

Dark matter is an elusive form of matter that almost never emits, absorbs or reflects light, while only weakly interacting with regular matter. These properties make it very difficult to detect using ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...

Anyone who has been paying attention to cosmology over the past few years is aware of problems with our best attempts to ...

Dark centre? A simulated version of the Milky Way galaxy. (Courtesy: AIP/ A. Khalatyan) Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation ...

Black hole discovery reshaped astrophysics by proving that some of the universe's most powerful objects cannot be seen directly but can be measured through their effects on space and time. Signals ...

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 ...
