SpaceTime with Stuart Gary Gary - Series 29 Episode 24 In this episode of SpaceTime, we uncover astonishing discoveries about the birth of black holes, a revolutionary Martian navigation system, and the arrival of NASA's SpaceX Crew 12 at the International Space Station. The Birth of a Black Hole: A New Perspective Astronomers have made a groundbreaking discovery by observing a star in the Andromeda Galaxy collapsing into a black hole without the expected supernova explosion. The star, catalogued as M31 2014 DS1, was seen glowing brightly in infrared light before fading away, leaving behind a dust shell. This event, which had been anticipated for decades, suggests that massive stars may collapse directly into black holes, challenging long-held assumptions about stellar deaths. The findings, published in the journal Science, provide new insights into the processes that govern black hole formation and indicate that such direct collapses may be more common than previously thought. NASA's New Martian Navigation System NASA has introduced an innovative navigation system for its Perseverance rover, allowing it to determine its location on Mars with remarkable precision—within 25 centimeters. The new technology, called Mars Global Localization, enables the rover to autonomously compare panoramic images with orbital terrain maps, eliminating the need for Earth-based assistance. This advancement significantly enhances the rover's ability to explore the Martian surface independently, paving the way for more extensive scientific investigations. SpaceX Crew 12 Arrives at the ISS NASA's SpaceX Crew 12 has successfully docked with the International Space Station, restoring the crew complement to seven members. The mission includes a diverse crew of two Americans, a Russian, and a French astronaut, who will conduct approximately 250 scientific experiments in orbit. Additionally, NASA has approved a sixth private mission to the ISS, slated for next year, which aims to support new research initiatives and infrastructure development for future human spaceflight missions. www.spacetimewithstuartgary.com ✍️ Episode References Journal Science, NASA Reports Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.

To find out more visit squarespace.com/spacetime  SpaceTime with Stuart Gary Gary - Series 29 Episode 23 In this episode of SpaceTime, we investigate the discovery of a nearly invisible galaxy dominated by dark matter, the latest delays in the Artemis 2 mission to the Moon, and the anticipated launch of Australia's new hypersonic scramjet. A Dark Matter Galaxy Unveiled Astronomers have identified an almost invisible galaxy, catalogued as CDG2, located in the Perseus galaxy cluster approximately 300 million light years away. This galaxy is believed to be composed of about 99% dark matter, making it one of the most dark matter-dominated galaxies ever detected. The findings, published in Astrophysical Research Letters, reveal that dark matter constitutes roughly 80% of the universe's total matter, and CDG2's faint presence was confirmed through observations of its globular clusters using NASA's Hubble Space Telescope and the European Space Agency's Euclid Space Observatory. Artemis 2 Mission Delayed Again NASA has announced another delay for the Artemis 2 mission, which aims to return humans to lunar orbit for the first time in over 50 years. A helium leak discovered in the Space Launch System (SLS) rocket's upper stage has prompted the agency to roll back the launch vehicle to the vehicle assembly building for repairs. This setback eliminates the potential for a March launch, with the next available windows opening in early April. The Artemis 2 mission will carry a crew of four on a 10-day journey to the Moon, including critical system tests and satellite deployments. Australia's Hypersonic Scramjet Launch Imminent An Australian company is set to test its new hypersonic scramjet-powered aircraft, the Dart AE, before the end of the month. This innovative vehicle will utilize a 3D printed Spartan Scramjet engine, designed to operate at speeds exceeding Mach 5 with liquid hydrogen fuel. The mission, codenamed Cassowary Vex, will launch aboard a Rocket Lab electron rocket and aims to validate the scramjet propulsion system under real hypersonic flight conditions while producing zero carbon emissions. www.spacetimewithstuartgary.com ✍️ Episode References Astrophysical Research Letters Become a supporter of this podcast:  https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.
