SpaceTime Series 27 Episode 115*How Black Holes Eat StarsAstronomers have developed a groundbreaking computer simulation detailing how supermassive black holes at the centres of galaxies can rip apart and consume entire stars. The study, published in the Astrophysical Journal Letters, provides new insights into the mysterious optical and ultraviolet emissions observed during these catastrophic events. Lead author Daniel Price from Monash University explains that the simulation captures the full evolution of the debris from a star being tidally disrupted by a black hole.*New Revelations About Earth’s MantleA new study reveals that the chemical composition of the Earth's mantle is uniform globally and only changes as it passes through different layers of crust closer to the planet's surface. Reported in the journal Nature Geoscience, the findings suggest that lavas from volcanic hotspots around the world likely originate from a worldwide uniform reservoir in the Earth's mantle.*Water More Widespread on the Moon
