    May 24 2024
    Venture into the cosmic depths with SpaceTime Series 27 Episode 63, where we unearth some of the universe's most ancient stars hiding in the halo of our very own Milky Way. These celestial elders, dubbed SAS stars, are remnants from a time when galaxies were just beginning to coalesce, offering a unique window into the universe's formative years. With their discovery, we edge closer to unraveling the mysteries of galaxy formation and the evolution of the cosmos.
    Next, we embark on a journey alongside Europe's JUICE spacecraft, now one year into its monumental eight-year voyage to the icy moons of Jupiter. This mission promises to probe the potential habitable environments beneath the moons' frozen crusts and could redefine our search for extraterrestrial life within our solar system.
    Finally, we witness Russia flexing its spacefaring muscles with the test launch of the new heavy-lift Angara A-5 rocket, aiming to usher in a new era for Russian space exploration and retire the venerable Proton rockets.

    S27E62: Earth's New Neighbor: Unveiling Speculus-3b in the Cosmic Backyard
    May 22 2024
    Set sail through the cosmic seas with SpaceTime Series 27 Episode 62, as we chart a course to a newly discovered Earth-sized exoplanet orbiting an ultra-cool red dwarf star just a stone's throw away in the galactic neighborhood. The discovery of Speculos-3b, a mere 55 light-years from Earth, stirs intrigue with its eternal days and nights due to likely tidal locking, offering a unique glimpse into the conditions of potentially habitable worlds around the most common stellar inhabitants of our galaxy.
    We then drift to the Milky Way's outskirts, where a stellar slow lane has been uncovered, challenging assumptions about the mass and dark matter content at the heart of our galactic home. This revelation, derived from Gaia and APOGEE data, suggests a lighter core and less dark matter than previously believed, sending ripples through our understanding of the cosmos.
    Our voyage continues as we seek to uncover dark matter's elusive influence on stellar streams with the help of the upcoming Vera C. Rubin Observatory. This bastion of observation promises to shed light on the ghostly gravitational effects of dark matter on these celestial ribbons, offering a new perspective on the most dominant yet unseen force in the universe.
    Join us on SpaceTime with Stuart Gary for a journey into these cosmic curiosities and more, as we navigate the mysteries of space and the wonders it holds.

  • S27E57: Rewriting Cosmic History: The Surprising Growth of Early Galaxies

    S27E57: Rewriting Cosmic History: The Surprising Growth of Early Galaxies
    May 10 2024
    Embark on a celestial odyssey with SpaceTime Series 27 Episode 57, where we unravel the rapid evolution of spiral galaxies.
    Our cosmic journey begins over 10 billion years ago, as new observations from the Webb Space Telescope reveal the early formation of star bars. These stellar structures, pivotal in the maturation of galaxies, were once thought to emerge in a chaotic young universe. Yet, they now appear to have developed far sooner, indicating a surprisingly orderly galactic evolution.
    The episode takes an unexpected turn as we delve into the moon's dramatic geological past. Discover how our lunar companion turned itself inside out, reshaping its surface with titanium-rich lava flows. The tale unfolds through a blend of computer simulations and spacecraft observations, shedding light on the moon's enigmatic lopsided geology.
    As we return to Earth, we witness the changing of the guard aboard China's Tiangong space station. The Shenzhou 17 crew's safe return after six months in orbit paves the way for the Shenzhou 18 team to continue exploring the frontiers of science in microgravity, including the intriguing endeavor of raising fish in the void.
    Concluding our cosmic survey, we gaze upon the night sky's wonders in the May edition of Skywatch. Marvel at the constellation Scorpius, the radiant Antares, and the Eta Aquarids meteor shower—a celestial spectacle born from the remnants of Halley's Comet.
