neutron star

Neutron stars are like huge natural dark matter detectors and might hold a key to helping us understand elusive dark matter. By observing a cold neutron star, physicists from the ARC Centre of Excellence for Dark Matter Particle Physics, might have vital information about the interactions between dark and regular matter, shedding light on the nature of this elusive substance. Dr. Sandra Robles of Fermilab is part of the collaboration on this research.

From Forbes, May 14, 2021: Fermilab senior scientist Don Lincoln discusses measuring the size of neutron stars and the result of a measurement showing that the centers of neutron stars are stiff and not squishy.
