In this episode, we embark on an exhilarating journey through the cosmos, exploring groundbreaking discoveries and developments that could reshape our understanding of the universe. We begin with a revelation about red giant stars, challenging long-held beliefs about how they spread life's essential elements across galaxies. New research on the star R Doradus suggests that powerful forces, rather than simple starlight pressure, are responsible for driving stellar winds, prompting a reconsideration of how galaxies are enriched.Next, we delve into the enigmatic world of hot Jupiters—gas giants that orbit perilously close to their stars. Recent studies indicate that many of these planets may have formed through a calmer process known as disk migration, providing insight into the evolution of planetary systems.Transitioning back to Earth, we provide a roundup of recent rocket launches, highlighting China's active role in space exploration and SpaceX's successful deployment of the CSG 3 satellite. As we shift our focus to Mars, we uncover the discovery of potential karst caves, which could harbor signs of ancient life, preserved from the planet's harsh surface conditions.We also celebrate the fourth anniversary of the James Webb Space Telescope, showcasing a stunning new video that offers an immersive tour of the cosmos, highlighting its remarkable contributions to astronomy.

SpaceTime with Stuart Gary - Series 28 Episode 154

In this episode of SpaceTime , we explore significant milestones in lunar exploration and the latest challenges in space technology.

Accelerated Launch for Artemis 2

NASA has moved up the launch date for the historic Artemis 2 manned moon mission to early February, marking the first human journey to the moon in over 50 years since Apollo 17. The Orion spacecraft, named Integrity, will embark on a 10-day mission, completing a free return trajectory around the moon. This episode discusses the mission's objectives, including in-space demonstrations and the deployment of five cubesats, as well as the importance of this mission for future lunar exploration and potential Mars missions.

New Insights from Lunar Rock Samples

Recent studies of lunar rock samples have revealed a new timeline for lunar impacts, pushing back the history of Earth's nearest celestial neighbour by 300 million years. The Apollo 17 rock sample, known as 76535, has provided crucial insights into the moon's formation and its geological history. Advanced computer simulations suggest that the impact that formed the Serenitatis Basin may have brought this rock to the surface, reshaping our understanding of the moon's bombardment history and its implications for Earth.

Japan's H3 Rocket Failure

The Japan Aerospace Exploration Agency (JAXA) has faced a setback with the failure of its new H3 rocket during a satellite launch. This follows a previous failure during its maiden flight. The H3 rocket, designed to replace the H2, aims to enhance Japan's capabilities in the global space market but has encountered significant technical challenges.

SpaceTime with Stuart Gary Gary - Series 28 Episode 153

In this episode of SpaceTime , we dive into thrilling new missions and groundbreaking discoveries in the universe.

Ramses Mission to Asteroid Apophis

The European Space Agency has greenlit an exciting new mission to study the infamous doomsday asteroid Apophis. The Ramses spacecraft will closely observe the 450-meter-wide asteroid as it makes a close flyby of Earth on April 13, 2029, at a mere 32,000 kilometers away—closer than many satellites. Initially feared to be on a collision course with Earth, further observations have since ruled out the threat of impact. However, the Ramses mission aims to understand how Earth's gravitational forces might affect Apophis during this close encounter, potentially setting the stage for future impacts. The spacecraft will deploy smaller probes to monitor changes in Apophis's orbit, rotation, and surface, providing vital data for planetary defense and insight into the evolution of asteroids.

Solving the Mystery of Existence

In a groundbreaking study, scientists at CERN have made strides in explaining the universe's existence by observing a slight imbalance in the behavior of matter and antimatter. This charge parity (CP) violation suggests that a tiny difference favored matter over antimatter during the Big Bang, allowing the universe to evolve into its current state. The findings, based on 80,000 decays of the Lambda beauty particle, indicate a significant deviation that could reshape our understanding of the cosmos.

The Largest Planetary Nursery Ever Seen

Astronomers have discovered the largest planetary nursery ever observed, located in a massive protoplanetary disk around a young star. This chaotic environment, cataloged as IRAS230776707, spans an astonishing 650 billion kilometers and showcases intricate structures that hint at the complex processes of planet formation. The observations, made using NASA's Hubble Space Telescope, reveal a unique perspective on how planetary systems may develop in extreme conditions, raising new questions about the dynamics shaping these disks.

In this episode, we dive into a myriad of exciting developments in the space industry and cosmology. We kick things off with a major shake-up as Blue Origin hires Tory Bruno, the former president and CEO of United Launch Alliance, to lead their new national security group. This strategic move signals Blue Origin's serious intent to compete for lucrative national security launch contracts, especially with their upcoming Glenn Heavy Lift rocket. Next, we explore a new and intriguing theory regarding dark matter, proposing that it may be composed of giant, star-sized objects, referred to as exotic astrophysical dark objects (IADs). Researchers are optimistic about detecting these objects through gravitational lensing, potentially using data from the Gaia Space Telescope. Shifting our focus, we discuss the upcoming close encounter of Asteroid Apophis with Earth in 2029, where the European Space Agency and JAXA will collaborate on the Ramses mission to study the asteroid's behavior under Earth's gravity. Understanding these interactions is crucial for future planetary defense strategies. We also tackle the mystery of missing normal matter in the universe. A recent study utilizing fast radio bursts has confirmed that a significant portion of this matter resides in the cosmic web, providing a monumental victory for cosmology by completing the census of normal matter. As we move closer to home, we highlight a groundbreaking dataset released by researchers at Lawrence Livermore Laboratory, mapping one million stable trajectories in the cis-lunar space. This open-source resource will aid future lunar missions and infrastructure planning. Finally, we preview the astronomical events of 2026, including a total solar eclipse, a total lunar eclipse, and exciting meteor showers, all set against a backdrop of high solar activity promising stunning auroras.
