Spacetime With Stuart Gary

SpaceTime Series 27 Episode 147*A Cosmic Glimpse into the Universe's PastAstronomers have witnessed a rare supernova, 2023 UFX, offering insights into the early universe. This unusual stellar explosion involved a metal-poor red supergiant star, providing clues about the cosmic conditions when the universe began. The study, led by Michael Tucker from Ohio State University, reveals how early supernovae seeded the next generation of stars, shaping galaxies like the Milky Way. The findings underscore the significance of dwarf galaxies as analogues for the universe's infancy, highlighting how metal-poor environments influenced star evolution and supernova behaviour.*Volcanic Mysteries on Jupiter's Moon IoA new study reveals that Io, Jupiter's volcanic moon, has active volcanoes at its poles, potentially regulating internal tidal heating. This discovery, based on NASA's Juno spacecraft data, sheds light on Io's intense volcanic activity and its role in planetary formation processes. Tidal heating, caused by gravita
