SpaceTime Series 28 Episode 20The Astronomy, Space and Science News PodcastNew Discoveries on Earth's Elements, Uranus's Moon Ariel, and the Fate of Comet AtlasIn this episode of SpaceTime, we delve into a groundbreaking study that challenges long-held beliefs about the origins of Earth's missing moderately volatile elements, such as copper and zinc. This research suggests that rather than being lost during the early formation of the solar system, these essential elements were likely retained by the first planetesimals and lost later due to violent cosmic collisions during planetary growth, reshaping our understanding of planetary chemistry and habitability.Uranus's Moon Ariel: A Window to Its InteriorWe also explore the fascinating trench-like features on Uranus's moon Ariel, which may serve as conduits for internal materials. New research indicates that these medial grooves could provide insights into Ariel's geological history and potential subsurface oceans, highlighting the complex interplay of tectonic and volcanic activities on the moon's surface.Comet Atlas: A Dying WonderAdditionally, we discuss the fate of Comet G3 Atlas, which has recently passed perilously close to the Sun, resulting in the fragmentation of its nucleus. As it fades from view, Atlas becomes a headless wonder, leaving behind a trail of debris that will continue to orbit the Sun. This episode also features a look at the stunning night skies of February, including the iconic constellations and celestial events to observe.00:00 Space Time Series 28 Episode 20 for broadcast on 14 February 202500:49 New insights into Earth's missing elements06:30 Trench-like features on Uranus's moon Ariel12:15 The demise of Comet G3 Atlas18:00 February night sky highlights22:45 The constellation Orion and its myths27:00 Exploring the Pleiades and other celestial wonders30:15 The significance of the Milky Way in stargazingwww.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

Earth's Water Origins, Bennu's Salty Secrets, and Marsquakes Unveiled: S28E19
SpaceTime Series 28 Episode 19The Astronomy, Space and Science News PodcastNew Insights into Earth's Water, Asteroid Bennu's Composition, and Marsquake TriggersIn this episode of SpaceTime, we investigate a groundbreaking study that challenges previous beliefs about when water arrived on Earth. New findings suggest that water may have come in during the later stages of Earth’s formation, providing fresh perspectives on the origins of life on our planet. The study highlights the importance of molybdenum isotopes in understanding the timing of water delivery and the conditions necessary for life.Searles Lake and Asteroid BennuWe also explore the intriguing similarities between Searles Lake in California and the asteroid Bennu, as researchers find that both environments share common water-soluble minerals. The Osiris Rex mission has revealed that Bennu's samples contain evaporite minerals formed under wet conditions, shedding light on the potential for life-sustaining elements in our solar system's past.Meteoroid Impacts and MarsquakesAdditionally, a new study indicates that meteoroid impacts may play a more significant role in triggering marsquakes than previously considered. Analyses from NASA's Mars InSight lander reveal that many seismic events on Mars could be linked to impacts, challenging existing assumptions about the planet's seismic activity.00:00 Space Time Series 28 Episode 19 for broadcast on 12 February 202500:49 Water arrival on Earth06:30 Searles Lake and asteroid Bennu12:15 Meteoroid impacts and Marsquakes18:00 Changes in men's height and weight22:45 Discovery of ancient bird fossils in Antarctica27:00 The best way to boil an egg30:15 AI and national security concernswww.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

Io's Volcanic Powerhouse, Ceres' Organic Origins, and the Quest for Distant Exoplanets: S28E17
SpaceTime Series 28 Episode 17The Astronomy, Space and Science News PodcastVolcanic Activity on Io, Ceres and the Building Blocks of Life, and New Exoplanet Search TechnologyIn this episode of SpaceTime, we explore the astonishing discovery of the largest volcanic hotspot ever observed on Jupiter's moon, Io. NASA's Juno mission reveals a feature that dwarfs Earth's Lake Superior and produces eruptions with six times the energy output of all the world's power plants. This unprecedented volcanic activity is driven by intense gravitational interactions with Jupiter, resulting in a dynamic landscape riddled with approximately 400 volcanoes.The Mystery of Ceres' Organic CompoundsWe also delve into new findings regarding the dwarf planet Ceres, where scientists have determined that organic deposits on its surface likely did not originate from its interior. Instead, these building blocks of life may have arrived through impacts from meteoroids, raising questions about the origins of life-sustaining compounds in our solar system.Advancements in Exoplanet Detection TechnologyAdditionally, we discuss the latest advancements in technology designed to search for Earth-like exoplanets. The newly developed coronagraph for NASA's Nancy Grace Roman Space Telescope will significantly enhance our ability to directly image distant planets by blocking out starlight, paving the way for future missions aimed at identifying habitable worlds beyond our solar system.00:00 Space Time Series 28 Episode 17 for broadcast on 7 February 202500:49 Discovery of a massive volcanic hotspot on Io06:30 Insights into organic compounds on Ceres12:15 New technology for exoplanet detection18:00 Omega-3 fatty acids and biological aging22:45 Infants' sense of smell development27:00 Tasmania's tallest trees documented30:15 Flat Earth theory and recent Antarctic explorationswww.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.
