The concept of habitable zones around black holes seems paradoxical, given the extreme conditions that define these cosmic entities. However, recent theoretical studies suggest otherwise, introducing ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

An illustration of a star that collapsed, forming a black hole. The black hole is at the center, unseen. Surrounding it is a dust shell moving away from the black hole and gas being pulled toward it. ...

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded ...

Using observations gathered by the James Webb Space Telescope (JWST), an international team of astronomers have revealed that one supermassive black hole in the early universe must have formed before ...

The study focuses in particular on dense concentrations of dark matter —often called "spikes" or "mounds"—that may form around massive black holes. By embedding their new relativistic description into ...

Astronomers examining data from the James Webb Space Telescope say they’ve spotted what might be the oldest black hole in the universe, born less than a second after the Big Bang. Their findings, ...

What are the little red dots discovered by the James Webb Space Telescope? These X-rays may offer a clue.

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth’s ...
