    Ancient Rocks and Cosmic Forces: Exploring Earth's Origins and the Hunt for a Fifth Force

    In this episode of SpaceTime, we delve into remarkable discoveries that illuminate the origins of our planet and the cosmos beyond. Ancient Australian Rocks Shed Light on Earth's Origins Scientists have made significant strides in understanding the formation of Earth and the Moon through the analysis of 3.7 billion-year-old feldspar crystals from the Murchison region in Western Australia. This research reveals that continental growth began relatively late in Earth's history, around three and a half billion years ago, suggesting a shared composition between Earth and the Moon following a colossal impact event. The findings challenge existing theories about the timing of crustal development and provide new insights into the early geological processes that shaped our planet. Hints of a Possible Fifth Force in Nature A groundbreaking report has emerged, suggesting the potential existence of a fifth fundamental force of nature. Researchers have observed unexpected deviations in electron transitions among calcium isotopes, hinting at a new particle, the Yukawa boson. This discovery could reshape the standard model of particle physics and deepen our understanding of the universe's fundamental forces, as scientists continue to explore the mysteries of atomic interactions. Record-Breaking Ocean Waves Observed from Space In an astonishing revelation, satellites have recorded ocean waves reaching heights of nearly 20 metres, the largest ever measured from space. This episode explores how these massive waves, driven by storms, can carry destructive energy across vast distances, impacting coastlines far from the storm's origin. The findings not only validate existing wave models but also reveal new insights into the energy dynamics of ocean swells. www.spacetimewithstuartgary.com ✍️ Episode References Nature Communications Physical Review Letters Proceedings of the National Academy of Sciences Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

    Auroras and Cosmic Craters: Unveiling Earth's Spectacular Space Weather and Impact Discoveries

    In this episode of SpaceTime, we explore the latest astronomical phenomena and significant discoveries that are shaping our understanding of Earth and space. Auroral Displays Light Up the Skies Planet Earth has been treated to an extraordinary display of auroras, with both the Aurora Australis and Aurora Borealis lighting up the skies following three powerful X-class solar flares, including an X 5.1 event on November 11. This segment dives into the mechanics behind these solar flares, the resulting coronal mass ejections (CMEs), and how they triggered spectacular auroras visible at lower latitudes than usual, including sightings as far north as Cairns and even Florida. Largest Modern Impact Crater Discovered Scientists have uncovered what is believed to be the largest modern impact crater on Earth, the 900-metre-wide Jinling Crater in southern China. This well-preserved structure, dating back to the Holocene epoch, offers new insights into extraterrestrial impacts and their effects on our planet. The discovery challenges previous assumptions about the frequency and scale of impacts from small celestial bodies and highlights the importance of studying such geological features. Nasa's Key Communications Dish Out of Service In a significant setback for NASA, the 70-metre Goldstone deep space communications dish has been rendered inoperable due to an accident that occurred in September. The incident has raised concerns about the strain on NASA's Deep Space Network, especially with upcoming missions like Artemis 2. We discuss the implications of this loss for various space missions and the efforts being made to mitigate the impact on communications. The Science Robert In our science report, we highlight a new projection from the World Meteorological Organisation indicating that 2025 is unlikely to be the hottest year on record, but it will rank among the top three. We also address public health concerns surrounding a measles alert in Australia, linked to declining vaccination rates, and the potential resurgence of preventable diseases. This segment underscores the importance of vaccination in maintaining herd immunity and protecting public health. www.spacetimewithstuartgary.com ✍️ Episode References Journal of Geophysical Research Nature Communications World Meteorological Organisation Reports Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.
