Researchers are now investigating gamma-ray burst jets and the surrounding cocoon formed by collapsed stars. This new framework suggests that high-energy photons can dissolve stellar material into neutrons, leading to the creation of heavy elements through a rapid neutron capture process. We discuss the implications of these findings and how they challenge long-held beliefs about nucleosynthesis in the universe.Shattering Beliefs About Asteroid VestaNext, we turn our attention to the asteroid Vesta, where a recent study published in Nature Astronomy reveals that its interior structure is far more uniform than previously thought. This discovery has led scientists to reconsider Vesta's identity, proposing that it may simply be a large asteroid rather than a protoplanet. We examine the research that challenges decades of assumptions about Vesta's formation and its role in understanding the early solar system.Did It Rain or Snow on Ancient Mars?Finally, we investigate the ancient climate of Mars, with a new study suggesting that geological formations on the planet were shaped by heavy precipitation, indicating a warmer and wetter past. This research utilizes computer simulations to analyze how rain and snow may have contributed to the development of Martian valleys and channels. We discuss the significance of these findings and their implications for our understanding of Mars's climatic history.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/0004-637XNature Astronomyhttps://www.nature.com/natureastronomy/Journal of Geophysical Research Planetshttps://agupubs.onlinelibrary.wiley.com/journal/21699356Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 New study provides clues explaining how exploding stars produce uranium and other heavy elements06:21 New study suggests giant asteroid Vesta is really just a big asteroid15:19 New study suggests heavy precipitation likely fed valleys on ancient Mars19:49 A new study warns that microplastic pollution could compromise ocean carbon22:17 More than 31,000 passwords belonging to Australian banks have been stolen24:47 Space Time is available every Monday, Wednesday and Friday through bitesz.com

This remarkable finding, published in the journal Nature Astronomy, marks the first detection of a molecular cloud using far ultraviolet emissions of molecular hydrogen. Eos, which is composed primarily of hydrogen, presents unique opportunities for studying the interstellar medium and the processes of star formation. We discuss the implications of this discovery and how it could reshape our understanding of molecular clouds across the galaxy.Jupiter's Polar Cyclones Under the MicroscopeNext, we delve into the latest revelations from NASA's Juno mission, which is providing new insights into Jupiter's ferocious polar cyclones and the volcanic activity on its moon Io. With fresh observations, scientists are uncovering the dynamics of Jupiter's atmosphere and the subsurface temperature profile of Io, shedding light on the gas giant's extreme weather patterns and the moon's geological activity.Out of Control Russian SpacecraftFinally, we discuss the impending re-entry of the Venera 8 spacecraft, a remnant of the Soviet era, which is expected to crash back to Earth on May 10. Launched in 1972, this spacecraft has been tumbling in low Earth orbit for over five decades. We examine the risks associated with its uncontrolled descent and the potential impact it may have upon re-entry.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Astronomyhttps://www.nature.com/natureastronomy/NASA Juno Missionhttps://www.nasa.gov/mission_pages/juno/main/index.htmlBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is space Time Series 28, episode 54 for broadcast on the 5th May, 202500:48 Astronomers have discovered a vast invisible molecular, gas and dust cloud near Earth12:40 Two key experiments are needed to help us understand the origin of Jupiter15:42 A failed Soviet spacecraft designed to land on Venus is about to crash on Earth19:00 New study claims people who use cannabis have higher risk of heart attack21:12 New study claims ghost lanterns in South Carolina may be caused by earthquakes
