Forget archaeologists and their lost civilizations, or paleontologists with their fossils—astrophysicist Heloise Stevance studies the past on an entirely different scale. When astronomers catch a ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

When the roiling nuclear fusion inside of a star begins to die — gravity crushing into the star’s waning fuel-store of hydrogen atoms, fusing them into heavier helium nuclei — the universe usually ...
