SpaceTime with Stuart Gary Gary - Series 29 Episode 3

In this episode of SpaceTime , we delve into the latest discoveries in astrophysics and the challenges faced by space agencies worldwide.

Ancient Supernova Offers Clues to Dark Energy

Astronomers have made significant strides in understanding dark energy, the enigmatic force driving the universe's accelerated expansion. A newly observed supernova, located 10 billion light years away, has been gravitationally lensed by a foreground galaxy, allowing scientists to analyze multiple images of the same explosion. This phenomenon could help determine the Hubble constant, shedding light on the universe's expansion rate and its ultimate fate, which ranges from a Big Crunch to a Big Rip.

Sterile Neutrino Hypothesis Nearly Ruled Out

After over a decade of research, scientists have come close to ruling out the existence of the sterile neutrino, a proposed particle that could explain anomalous neutrino behavior. Data from the Micro BooNE experiment at Fermilab has shown no signs of sterile neutrinos, providing a pivotal moment in particle physics that narrows the search for new theories beyond the standard model.

China's Reusable Rocket Setback

China's efforts to develop a reusable rocket faced a significant blow as its Long March 12A failed on its maiden flight. Although the rocket's first and second stages performed as expected, the first stage failed to return successfully, highlighting the challenges in achieving reusability akin to SpaceX's Falcon 9. This setback underscores the competitive nature of the global space industry as China strives to enhance its capabilities.

SpaceTime with Stuart Gary Gary - Series 29 Episode 2

In this episode of SpaceTime , we explore the intriguing history of our galaxy and the secrets of Earth's early water retention.

Unraveling the Milky Way's Chemical Bimodality

A groundbreaking study suggests that the Milky Way's stellar formation and its unique chemical bimodality may stem from intergalactic gas rather than traditional star formation or galactic collisions. Researchers utilized advanced computer simulations to analyze the formation of 30 simulated galaxies, revealing that the Milky Way's distinct groups of stars, defined by their iron and magnesium content, can emerge through various mechanisms. This research not only enhances our understanding of the Milky Way's evolution but also challenges previous assumptions about the role of smaller galaxies in shaping its chemical structure.

Earth's Mantle: A Reservoir of Ancient Water

New findings indicate that Earth's mantle may have locked away vast amounts of water during the planet's formative magma ocean phase. Researchers discovered that bridgmanite, the most abundant mineral in the mantle, could store significant quantities of water, potentially equating to the volume of all today's oceans. This study reshapes our understanding of how water was retained during Earth's extreme early conditions and its role in the transition to a habitable planet. The implications of this research may provide insights into the geological processes that sustain Earth's dynamic environment.

The Astronomy of Standing Stones

Reflecting on archaeological astronomy, we revisit a pivotal study that revealed how ancient standing stones in Britain were constructed with astronomical alignments in mind. This research confirms that the earliest stone monuments, including the Great Circles of Scotland, were intentionally oriented to mark the movements of the sun and moon. By examining the patterns of alignment, researchers established a connection between these ancient structures and the cultural significance of celestial events, illustrating the sophisticated understanding early Britons had of their environment and the cosmos.
