As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and structure, potentially revealing clues as to what lies within them.

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

Sixteen years ago, theoretical astrophysicists at UC Berkeley and elsewhere proposed that highly magnetized, spinning neutron stars — magnetars — were the power source behind some superluminous ...
