Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or neutron star slams into the universe's hottest class of star.

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

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 ...

A black hole isn’t actually a hole at all; it’s an incredibly dense object where a huge amount of matter is squeezed into a ...

The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...

The nature of black holes has long been shrouded in mystery, but some astronomers believe the answers are a lot closer to home than expected. A fringe astronomical theory known as "black hole ...

We all know that everything kicked off when the Big Bang exploded our universe into reality, right? Well, not necessarily. A compelling new theory of the creation of our universe suggests that it may ...

"If our hypothesized dark charge is true, then we believe there could be a significant population of primordial black holes, which would be consistent with other astrophysical observations, and ...

By stopping black holes from fully evaporating, hidden dimensions may solve a cosmological paradox.

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.
