Prepare for a cosmic revelation in SpaceTime Series 27 Episode 49, as we journey through the Milky Way to uncover a celestial heavyweight—the most massive stellar black hole ever discovered in our galaxy. Detected by the vigilant eyes of the European Space Agency's Gaia mission, this black hole, known as Gaia BH3, imposes a peculiar wobble on its companion star, betraying its presence. Weighing in at a colossal 33 solar masses and residing a mere 2,000 light-years away in the constellation Aquila, BH3 redefines our understanding of stellar remnants and the mysterious dance of gravity and mass that shapes them.Then, we take a detour through the evolutionary tracks of white dwarf stars, which have long been the cooling embers of the cosmic campfire. Recent observations from Gaia have spotted a group of these stellar corpses defying the natural order, mysteriously ceasing to cool. This perplexing behavior is challenging astronomers to rethink the very nature of these ancient stars, which may not be the reliable cosmic clocks once thought.We'll also explore the technological advancements propelling humanity's reach into the cosmos with the development of a new, more capacious Cygnus cargo ship. Set to enhance supply missions to the International Space Station, this vessel promises to double the payload space and carry up to five tonnes of cargo, marking a significant leap forward in our orbital endeavors.And in our Science Report, we celebrate the end of the 2023-24 El Niño weather pattern, but with a watchful eye on the horizon for a potential return to La Niña conditions. Plus, we delve into the health risks of sugary and artificially sweetened drinks, the discovery of a jaw-droppingly large marine reptile, and the curious case of an extensive paranormal archive that sparks more questions than answers.For the full cosmic journey, visit our website at https://spacetimewithstuartgary.com and support the show at https://www.spreaker.com/show/spacetime.

S27E49: Black Hole Titans: Gaia's Gaze Reveals a New Cosmic Champion

Embark on an astronomical odyssey with SpaceTime Series 27 Episode 48, as we unveil the most detailed view of the expanding universe to date. The first-year data from DESI, the Dark Energy Spectroscopic Instrument survey, is in, and it's changing the cosmic game. This groundbreaking five-year study is mapping the universe in 3D, charting the enigmatic influence of dark energy over time. Will the universe meet a chilling big freeze, or will dark energy's relentless acceleration lead to a catastrophic big rip? With precision better than 1%, DESI's data is painting a complex picture of our cosmic destiny.Then, join us in celebrating a celestial milestone as the Solar Observatory spacecraft SOHO captures its 5000th comet. SOHO's unexpected role as a prolific comet hunter has deepened our understanding of these enigmatic sun-grazers, offering insights into the sun's atmosphere and the large-scale structure of comets.Plus, we follow the Soyuz MS-24 capsule's return to Earth, bringing home a NASA astronaut and the first Belarusian cosmonaut after a landmark mission. With blue skies over Kazakhstan, the Soyuz's journey from the International Space Station to the steppe marks a successful conclusion to an expedition of cosmic proportions.And don't miss our Science Report, where we delve into the impact of climate change on wine regions, the link between mood disorders and driving in young people, and the debate over a meteor impact ejecta potentially being alien technology.For more SpaceTime and to support the show, visit our website at https://spacetimewithstuartgary.com.

S27E48: Cosmic Cartography: Charting Dark Energy's Role in the Universe's Fate

Prepare to illuminate the shadowy frontiers of space in SpaceTime Series 27 Episode 47. We begin by shedding light on new findings that reveal brown dwarfs, those celestial enigmas straddling the line between the largest planets and the smallest stars, are far more star-like than we ever imagined. Born from the same intricate dance of gas and dust that gives rise to stars, these failed stars have a story more intertwined with their luminous kin than previously thought. Next, we peer into the future, where the clock is ticking down to an explosive cosmic event. Astronomers eagerly anticipate a nova eruption within a binary star system, set to dazzle the skies sometime before year's end. This stellar spectacle, a cyclical detonation on the surface of a white dwarf, promises to be a beacon in the night, echoing observations that date back over a century.We then voyage to the extreme starburst galaxy M82, a crucible of creation churning out new stars at a rate tenfold that of our own Milky Way. With the James Webb Space Telescope piercing through the cosmic dust, we get a front-row seat to the galactic winds and star-forming frenzy defining this compact powerhouse of a galaxy.And in the Science Report, we delve into the role of homosexual behavior in mammalian social bonding, the alarming rise in simultaneous heatwaves and sea level extremes on global coastlines, the potential psychological effects of teenage screen time, and the latest in home entertainment and security tech that's shaping our digital lives.For the full cosmic journey, visit our website at https://spacetimewithstuartgary.com and support the show at https://www.spreaker.com/show/spacetime.

S27E47: Stellar Nurseries: Unveiling the Origins of Brown Dwarfs and Starbursts

SpaceTime Series 27 Episode 46: The Cosmic Dance of Neutron Stars and Black HolesJoin us on a thrilling journey through the cosmos in SpaceTime Series 27 Episode 46, where we delve into the mysteries of a possible neutron star-black hole merger detected in gravitational waves. The LIGO-Virgo-KAGRA collaboration may have stumbled upon a cosmic ballet between the densest objects in the universe, offering tantalizing clues about the elusive mass gap and challenging our understanding of stellar evolution.Next, we explore the cannibalistic tendencies of stars as a new study reveals that stars often end up devouring their own planets. This celestial feast, found in roughly 8% of binary star systems examined, raises questions about the stability of planetary orbits and could reshape our knowledge of cosmic dynamics.And as North America was plunged into darkness by a total solar eclipse, scientists seized the opportunity to conduct groundbreaking research. From rockets piercing the upper atmosphere to jets chasing the eclipse at dizzying altitudes, we look at the scientific endeavors that took advantage of this spectacular celestial event.Plus, in the Science Report, we discuss the implications of "forever chemicals" in our water resources, the heart failure benefits of a diabetes drug, the discovery of Australia's oldest pottery, and the controversy surrounding a prestigious clinic's endorsement of Reiki.For more SpaceTime and to support the show, visit our website at https://spacetimewithstuartgary.com, where you can access our universal listen link, find show notes, and learn how to become a patron.
