SpaceTime with Stuart Gary SpaceTime

Join us for SpaceTime Series 27 Episode 66, where we delve into the latest cosmic discoveries and technological challenges shaping our understanding of the universe.
First, we explore a glitch aboard the BepiColombo spacecraft bound for Mercury. The joint ESA-JAXA mission faced a sudden issue with its thrusters, impacting its journey towards the innermost planet. Despite the setback, mission control has restored 90% of the spacecraft's thrust capabilities, ensuring BepiColombo's arrival at Mercury for its next gravity assist.
Next, we turn our attention to Venus, where BepiColombo's fleeting visit has unveiled surprising insights into the planet's atmosphere. Observations reveal that carbon and oxygen ions are escaping Venus's upper layers at speeds sufficient to overcome the planet's gravity, offering new clues about atmospheric loss mechanisms.
Finally, we discuss new evidence explaining the mysterious phenomenon of stars that suddenly vanish without the usual supernova explosion. This complete stellar collapse turns massive stars directly into black holes, providing fresh perspectives on stellar evolution.

Join us for SpaceTime Series 27 Episode 65, where we uncover the latest cosmic revelations and scientific advancements.
First, we delve into the intriguing new features discovered in high-resolution images of Jupiter's icy moon Europa. Captured by NASA's Juno spacecraft, these images reveal signs of plume activity and ice shell disruption, providing clues about the moon's subsurface ocean and its potential to support life.
Next, we explore a groundbreaking model explaining the formation of free-floating planets. Recent findings suggest that gravitational perturbations in dense star clusters could eject giant planets, leading them to orbit each other as they drift through interstellar space.
Finally, we report on NASA's Perseverance rover, which has collected its 24th rock sample on Mars. This new sample, rich in carbonate and silica, holds promise for understanding the Red Planet's ancient habitability and potential signs of past life.

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.
Join us on SpaceTime with Stuart Gary for a cosmic exploration that spans from our galactic neighborhood to the far reaches of the Jovian system, and beyond.

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.
