    Anna Frebel: Origin and Evolution of the Universe, Galaxies, and Stars | Lex Fridman Podcast #378

    Anna Frebel, Lex Fridman

    MIT astrophysicist Anna Fabel employs stellar archaeology via high-resolution spectroscopy to analyze ancient stars like HE 1327-2326 and HE 1523-0901, reconstructing the chemical evolution of the early universe. Her research identifies specific neutron star mergers as the origin of heavy elements and uses retrograde stellar motion to trace the Milky Way's hierarchical formation from accreted dwarf galaxies. Beyond her technical work on cosmic timelines, Fabel highlights historical contributions by women scientists such as Cecilia Payne-Gaposchkin and Lisa Meitner to emphasize the human context of astronomical discovery.
