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 new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in the sky. But no one knows whether the ...

Nearly every massive galaxy observed hosts a supermassive black hole at its center. NASA’s James Webb Space Telescope has discovered that some of these supermassive black holes may even be too big for ...

Black holes represent some of the most extreme environments in the universe. They are the sources of the strongest gravitational fields, allowing us to test Einstein's theory of general relativity to ...

Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...

Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of general relativity breaks down inside black holes, either by the presence of a so ...

Scientists say they have detected evidence of cosmic-scale wind coming from a supermassive black hole at the center of our galaxy, potentially solving one of the longest-standing mysteries in ...

A runaway black hole leaving a streak of new stars in its wake. James Webb Space Telescope / van Dokkum et al. Last year, astronomers were fascinated by a runaway asteroid passing through our Solar ...

There are black holes that are too big to be born from the death of a star but aren’t quite supermassive either. There’s finally evidence for where those came from. The evolutionary theory of stars ...
