A study suggests an unusual LIGO gravitational wave signal may be evidence of a primordial black hole, a long-hypothesized ...

Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests the missing ...

Two experiments designed to detect signals directly found no evidence for the signal reported by an earlier experiment.

The Big Bang may not mark the absolute beginning of everything. A controversial cosmological model instead treats it as a ...

For decades, dark matter has been treated as the unseen framework around which galaxies take shape. Even the smallest galaxies are generally thought to be wrapped inside vast halos of it, with the ...

"With the launch of the ten-year Legacy Survey of Space and Time, the Rubin Observatory is opening a new window on the ...

A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. There are two main types of black hole; stellar mass and supermassive black holes, and they ...

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 ...

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 ...

Astronomers at the Center for Astrophysics | Harvard & Smithsonian have proposed a new explanation for some of the universe's most puzzling early galaxies, nicknamed "little red dots." In the study, ...

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 ...
