Despite their small diameters—about 12.5 miles (20 kilometers)—neutron stars boast nearly 1.5 times the mass of our sun, and are thus incredibly dense. Just a sugar cube of neutron star matter ...

Using a model for the Milky Way's mass distribution and the observed positions and velocities of stars, they not only calculated the orbits of stars but, more importantly, measured how much mass ...

Stellar-mass black holes form from the death of massive stars and have already been found via a variety of different techniques. Supermassive black holes are found at the centres of large galaxies ...
