• Exoplanet Discovery, Dark Energy Evolution

  SpaceTime Series 28 Episode 37The Astronomy, Space and Science News PodcastExciting New Exoplanet Discovery, Evolving Dark Energy, and Insights into the Moon's Magnetic FieldIn this episode of SpaceTime, we uncover the discovery of a potential new exoplanet, TOI 2818C, located over a thousand light years away in the constellation Papus. This intriguing planetary candidate is estimated to be 10 to 16 times the size of Earth and orbits its host star in less than 16 Earth days. We delve into the innovative transit timing variations method employed by astronomers, which revealed the presence of this companion planet alongside the hot Jupiter TOI 2818b, and discuss the implications for our understanding of planetary formation in hot Jupiter systems.Dark Energy's Mysterious EvolutionWe also explore a groundbreaking study suggesting that dark energy may be evolving over cosmic time scales. Utilizing data from the Dark Energy Spectroscopic Instrument (DESI), scientists are piecing together the largest three-dimensional map of the universe, revealing hints that dark energy's influence could be changing. This discovery could challenge current cosmological models and reshape our understanding of the universe's fate.Dynamic Lunar Magnetic FieldAdditionally, we examine findings from China's Chang'e 6 mission, which indicate that the Moon's magnetic field has been more dynamic and lasted longer than previously thought. The analysis of lunar samples reveals a resurgence of the magnetic field around 2.8 billion years ago, suggesting that the Moon's interior remains geologically active, challenging earlier beliefs about its magnetic history.00:00 Space Time Series 28 Episode 37 for broadcast on 26 March 202500:49 Discovery of exoplanet TOI 2818C06:30 Transit timing variations method explained12:15 Implications for hot Jupiter planetary systems18:00 Evolving dark energy and the DESI findings22:45 Insights into the Moon's magnetic field dynamics27:00 Summary of recent astronomical discoveries30:15 Discussion on the health impacts of sugary beverageswww.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.
