In this episode of SpaceTime, we uncover groundbreaking insights into Earth's mysteries and the cosmos beyond. Mysterious Structures in Earth's Mantle A new study reveals that enigmatic structures within Earth's mantle may hold vital clues about why our planet evolved the conditions necessary for life. These massive formations, known as large low shear velocity provinces and ultra low velocity zones, reside at the boundary between the mantle and outer core, approximately 2,900 kilometres beneath the surface. The research suggests these anomalies could be remnants of Earth's formative processes, providing a deeper understanding of how elements from the core influenced the planet's cooling, volcanic activity, and atmospheric evolution, ultimately setting Earth apart from Venus and Mars. Unprecedented View of the Milky Way Astronomers have achieved a remarkable new perspective of our home galaxy, the Milky Way, with the largest low-frequency radio image ever assembled. This extensive survey, conducted using the Murchison Wide Field Array radio telescope in Western Australia, captures the intricate birth, evolution, and demise of stars across the southern hemisphere. The new image, which boasts double the resolution and tenfold sensitivity compared to previous observations, offers valuable insights into stellar interactions and the cosmic landscape, revealing patterns in star formation and supernova remnants. Successful Return of Stranded Taikonauts In a significant development, the three Chinese taikonauts stranded in orbit after their Shenzhou 20 spacecraft was struck by space debris have safely returned to Earth aboard the Shenzhou 21 capsule. The crew's return marks the end of a six-month mission at the Tiangong space station, with their extended stay setting a new record for the longest duration in space for Chinese astronauts. The episode highlights the challenges of space travel and the rapid response by Beijing to ensure crew safety. www.spacetimewithstuartgary.com ✍️ Episode References Nature Geoscience Publications of the Astronomical Society of Australia New England Journal of Medicine Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

    Cosmic Beginnings and Stellar Discoveries: Unveiling the First Stars and Secrets of the Moon

    (00:00:00) Cosmic Beginnings and Stellar Discoveries: Unveiling the First Stars and Secrets of the Moon (00:00:47) Have astronomers finally seen the universe’s first stars (00:04:06) Hidden secrets about the Moon and the asteroid Vesta (00:10:45) Euclid peers deep into a stellar nursery full of baby stars (00:16:05) The Science Report (00:18:09) Skeptics guide to flat earthers falling flat on their face again In this episode of SpaceTime, we uncover groundbreaking findings that could reshape our understanding of the universe's early stars, the Moon's hidden secrets, and the asteroid Vesta's internal structure. First Stars Detected Astronomers may have finally glimpsed the universe's first stars, known as Population 3 stars, thanks to observations from NASA's Webb Space Telescope. These luminous giants, formed just 200 million years after the Big Bang, are believed to have ended the cosmic dark ages and initiated the epoch of reionisation. The episode delves into the significance of these findings, which suggest that these stars were formed in small clusters and exhibit extremely low metallicity, challenging previous theories about the early universe. Secrets of the Moon Revealed Two NASA studies have provided fascinating insights into the Moon's internal structure through advanced gravity modelling. By analysing data from the GRAIL mission, researchers have created the most detailed gravitational map of the Moon to date, revealing variations linked to tidal deformation. This research offers clues about the Moon's geological history and volcanic activity, particularly highlighting differences between the near and far sides of the Moon. New Insights into Asteroid Vesta In a parallel study, scientists examined the asteroid Vesta's structure using data from NASA's Dawn spacecraft. Contrary to earlier beliefs of a layered interior, new measurements suggest Vesta may have a more uniform composition, with only a small core, if any. This revelation challenges long-held assumptions about the formation and evolution of this ancient asteroid. Euclid Space Telescope's Stellar Nursery Observations The European Space Agency's Euclid Space Telescope has peered into the dark cloud LDN 1641, uncovering a vibrant stellar nursery filled with young stars.
