In a recent Nature paper, scientists have observed that material surrounding the pulsar distorts the light emitted from the pulsar. The material focusses the light, increasing the observed brightness of the pulsar. A neutron star is part of the later life of a star’s lifetime. To give you an idea of how dense a neutron star is, a sugar cube of neutron star material would weigh about 1 billion tons. Even though the telescopes used were built decades ago, the advancements in computing have allowed scientists to see into our Universe with greater detail.
