title: ASTROPHYSICS: Signs of Extreme Gravity.
abstract: Neutron stars are among the densest objects in the universe, and observations of processes in their vicinity may provide insights into conditions of extreme gravity. Morsink highlights recent observations with the Rossi X-ray Timing Explorer satellite, which are difficult to explain with existing theories.
