SpaceTime with Stuart Gary Gary - Series 28 Episode 147 In this episode of SpaceTime , we delve into remarkable discoveries that significantly enhance our understanding of the cosmos. Longest Gamma Ray Burst Ever Detected Astronomers have made headlines with the discovery of the longest gamma ray burst ever recorded, GRB 250702B, which lasted over seven hours. This unprecedented event is reshaping our understanding of stellar explosions and their aftermath. Initial observations indicate that this extraordinary burst may have originated from a black hole consuming a star, prompting new theories about the mechanisms behind these powerful cosmic phenomena. We explore the implications of this finding and how it challenges existing models of gamma ray bursts. Elemental Bounty in Supernova Remnant For the first time, scientists have detected chlorine and potassium in the remnants of the supernova Cassiopeia A, utilizing the advanced capabilities of the CRISM spacecraft. This discovery sheds light on the elemental processes that occur during stellar explosions and their connection to the formation of elements crucial for life on Earth. We discuss the significance of these findings and their impact on our understanding of stellar nucleosynthesis.

In this episode of SpaceTime , we explore significant developments in space exploration and cosmic studies that could reshape our understanding of the universe. Nasa's MAVEN Mars Orbiter: Communication Loss NASA's MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft has gone silent, with contact lost on December 6th after passing behind Mars. The orbiter has been a vital asset for over a decade, studying the Martian atmosphere and solar wind interactions that have transformed Mars from a water-rich world to a cold desert. We delve into MAVEN's critical findings, including the mechanisms of atmospheric escape and the implications of its potential loss for ongoing Martian research. Galactic Neighbourhoods: Influencing Evolution A new study reveals how a galaxy's local environment can significantly affect its evolution. The research, published in the Monthly Notices of the Royal Astronomical Society, demonstrates that galaxies situated in densely populated regions tend to grow more slowly and develop different structures compared to their isolated counterparts. By analysing data from the Deep Extragalactic Visible Legacy Survey, astronomers have gained insights into the complex dynamics of galactic interactions and their impact on star formation rates. Uranus and Neptune: More Richie than Icy? Challenging long-held classifications, a recent study suggests that the solar system's ice giants, Uranus and Neptune, may actually be more rocky than icy. Researchers from the University of Zurich conducted computer simulations that indicate a broader range of internal compositions for these planets, which could explain their complex magnetic fields. This new perspective could alter our understanding of planetary formation and evolution, paving the way for future explorations of these distant worlds. www.spacetimewithstuartgary.com (https://www.spacetimewithstuartgary.com/) ✍️ Episode References Monthly Notices of the Royal Astronomical Society NASA TV Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support (https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .
