Starship Catastrophe: The Latest Test Flight Explosion and Its Implications
In this episode of SpaceTime, we explore some of the most recent and intriguing developments in space exploration and cosmic phenomena.Starship's Latest Test Flight Ends in ExplosionSpaceX faces another setback as its 10th Starship test flight ended in a massive explosion at the Massey test stand in Boca Chica, Texas. The incident occurred just minutes before a planned static fire test of the upper stage. We discuss the details of the explosion, including early indications of a cryogenic methane leak and the implications for SpaceX's ambitious goals of interplanetary transport.A Cosmic Anomaly and Its Frightening Implications for EarthA newly discovered cosmic anomaly challenges our understanding of galaxy evolution. A distant spiral galaxy, housing a supermassive black hole billions of times the mass of the Sun, is emitting colossal radio jets stretching over 6 million light years. This finding raises alarming questions about the potential future of our own Milky Way and the dangers posed by similar jets originating from Sagittarius A, our galaxy's supermassive black hole. We delve into the study's findings and their implications for life on Earth.New Insights into Neutron StarsA groundbreaking study has provided new insights into the birth masses of neutron stars, revealing that they typically form with a mass around 1.3 times that of our Sun. Using advanced modeling techniques, researchers analyzed a sample of neutron stars in binary systems to understand their formation history better. This research opens up new avenues for interpreting gravitational wave detections and understanding the lifecycle of massive stars.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical Societyhttps://academic.oup.com/mnrasNature Astronomyhttps://www.nature.com/natureastronomy/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 75 for broadcast on 23 June 202501:00 Starship's latest test flight ends in explosion12:15 A cosmic anomaly and its frightening implications for Earth22:30 New insights into neutron stars30:00 Science report: Cannabis use linked to increased cardiovascular disease risk
