Cosmic Giants: Unveiling the Universe's Largest Particle Cloud
In this episode of SpaceTime, we uncover groundbreaking discoveries and innovative advancements in the realm of space and planetary science.Record-Breaking Cosmic Structure DiscoveredAstronomers have imaged an unprecedented cosmic structure, a massive cloud of energetic particles surrounding a galaxy cluster that spans nearly 200 million light years. This remarkable finding, presented at the 246th meeting of the American Astronomical Society, challenges existing theories about particle energization, suggesting that giant shock waves and turbulence are at play rather than nearby galaxies. We delve into the implications of this discovery for our understanding of cosmic magnetic fields and the dynamics of galaxy clusters.A New Approach to Building MarsA recent study has revealed a novel method for planetary core formation, suggesting that molten sulfide rather than metal could create a core in rocky planets like Mars. This research, published in Nature Communications, offers fresh insights into the early evolution of terrestrial worlds, particularly in sulfur-rich environments. We discuss how this finding could reshape our understanding of Mars's geochemical timeline and its core formation process.High-Performance Infrared Nano AntennasScientists have developed innovative gold nano antennas that significantly enhance the capabilities of thermal infrared cameras, improving image quality and sensitivity.

These beads, with their unusually high magnesium content, may originate from the Moon's mantle, offering scientists their first direct glimpse into this elusive layer. We discuss the implications of this discovery for understanding lunar geology and the history of our celestial neighbor.Unusual Stellar Nursery Discovered Near the Milky Way's CenterNew findings indicate that star formation rates near the galactic center of the Milky Way are unexpectedly low, despite the high density of stellar material. Utilizing data from NASA's retired SOFIA observatory, researchers have identified that these regions may produce only one generation of stars, challenging traditional models of stellar nurseries. We explore what these revelations mean for our understanding of galactic dynamics and star formation processes.Another Lunar Lander Crashes on the MoonThe Japanese I Space lunar lander, Resilience, has tragically crashed during its landing attempt on the Moon, marking another setback in the race for lunar exploration. We delve into the details surrounding the mission's failure and the ongoing investigations aimed at uncovering the cause of the crash. This incident highlights the challenges faced by commercial space missions as they strive to achieve successful lunar landings.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvAstrophysical Journalhttps://iopscience.iop.org/journal/0004-637XBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 72 for broadcast on 16 June 202501:00 A new window into the Moon's hidden mantle12:15 Unusual stellar nursery discovered near the Milky Way's center22:30 Another lunar lander crashes on the Moon30:00 Science report: New insights into the mystery of why cats purr
