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.
