Is the universe a fractal?
For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes. Look, it's complicated.

Observations detect young and energetic pulsar in a supernova remnant
An international team of astronomers has reported the discovery of a new pulsar, which received the designation PSR J1631–4722. The newfound pulsar, which is young and energetic, turns out to be associated with a supernova ...
Quantum correlations could solve the black hole information paradox
The black hole information paradox has puzzled physicists for decades. New research shows how quantum connections in spacetime itself may resolve the paradox, and in the process leave behind a subtle signature in gravitational ...

Latest gravitational wave observations conflict with expectations from stellar models
Almost 300 binary mergers have been detected so far, indicated by their passing gravitational waves. These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging ...
Clever trick to cook young stars detected for first time—astronomers highlight magnetic fields as the missing ingredient
The missing ingredient for cooking up stars in the same way you might steam your Christmas pudding has been spotted for the first time by astronomers. Much like a pressure cooker has a weight on top of its lid to keep the ...
