The first-ever image of a black hole—a glowing, ring-like structure at the heart of galaxy M87—was unveiled to the world in a landmark moment in 2019. Now, researchers have taken the next big ...

A starship driven by a captive black hole sounds like pure science fiction, yet the underlying physics is brutally literal. A tiny, artificial singularity would convert mass into energy with an ...

Learn more about the images advanced telescopes could take of black holes and how they could back up Einstein’s general theory of relativity. In 2019, the Event Horizon Telescope (EHT) released the ...

We cannot escape the dimensions of the classical Universe – three spatial directions and the inexorable march of time. But gravity may not be bound by the same rules that apply to flesh and stone. It ...

Black Holes are called black because light cannot escape from inside their event horizons. Astronomers nevertheless detect black holes indirectly through their effects on nearby matter, gravitational ...

For four years, little red dots (LRDs) have been the hottest topic in astrophysics. Astronomers first noticed them in observations that NASA’s James Webb Space Telescope (JWST) made in 2022. The LRDs ...

Star is about to transform into a black hole. And we’re about to travel inside it to see what’s on the other side. The only problem is that we’ll never be able to report our findings back to Earth.

Black holes have been understood as infinite singularities for a century. In 1916, months after Einstein published general relativity, Karl Schwarzschild did something that surprised even Einstein ...
