Much remains a mystery about the first billion years of the universe’s history, the epoch in which the cosmos emerged from its dark ages with the dawning of the earliest stars and galaxies. Now ...

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, ...

If you could sit perfectly still in a patch of space far from any stars, planets, or particles — utter emptiness — you might expect nothing at all to happen. No heat, no sound, no light. But the ...

Surprisingly, some of the universe's brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a ...

The Anderson transition is a phase transition that occurs in disordered systems, which entails a shift from a diffusive state (i.e., in which waves or particles are spread out) to a localized state, ...
