Unveiling TOI 2818C: A New Exoplanet Discovery, Insights into Hot Jupiters, and the Dynamics of Planetary Systems - Full Unedited Interview
In this Bonus episode of SpaceTime, we delve into the exciting discovery of a potential new exoplanet, TOI 2818C, located over a thousand light years away in the constellation Papus. This intriguing planetary candidate is estimated to be 10 to 16 times the size of Earth and completes its orbit in less than 16 Earth days. We discuss the innovative transit timing variations method that led to this discovery, revealing the presence of this companion planet alongside the hot Jupiter TOI 2818b, and its implications for our understanding of planetary formation in hot Jupiter systems.
Understanding Hot Jupiters
We explore the unique characteristics of hot Jupiters and the rarity of finding companion planets within their systems. As we analyze the dynamics involved when multiple planets influence each other's orbits through gravitational interactions, we uncover the challenges astronomers face in deciphering these complex systems.
Planetary Formation Theories
Additionally, we examine the ongoing debates surrounding the formation of hot Jupiters, including the theories of cold and hot migration. These concepts help explain how these gaseous giants, which were the first exoplanets discovered, can exist so close to their host stars and provide insight into the broader mechanisms of planet formation.

Unveiling the World's Oldest Meteor Impact Crater, Insights into Earth's Ancient History, and the Role of Impacts in Life's Origins
In this episode of SpaceTime, we delve into the groundbreaking discovery of the world's oldest known meteor impact crater, located in the North Pole Durham region of Western Australia. Dating back an astonishing 3.5 billion years, this ancient structure challenges previous assumptions about Earth's geological history and the origins of life. We discuss the implications of this significant find, as researchers believe it could reshape our understanding of crust formation and the environmental conditions that may have fostered early microbial life.
Shatter Cones and Ancient Impacts
Join us as we explore the evidence provided by shatter cones—distinctive rock formations that form under the immense pressure of a meteor strike. The discovery of these features, alongside the crater's massive size, suggests that such impacts were not only common but also played a crucial role in shaping the early Earth. We examine how these ancient events could have influenced the development of cratons and the mineral wealth found in regions like Western Australia.
Impacts and the Evolution of Life
Additionally, we discuss how these impact events may have created environments conducive to life, such as hot water pools rich in mineral nutrients. The episode highlights the importance of recognising the role of giant impacts in Earth's history and how they may have contributed to the emergence of life as we know it today.

Evidence of Ancient Martian Oceans, Insights from Zhurong Rover, and Implications for Life on Mars
In this bonus interview from SpaceTime, we delve into the groundbreaking findings from China's Zhurong Mars rover, which has confirmed the existence of ancient ocean beaches in the northern hemisphere of Mars. Recent studies published in the Proceedings of the National Academy of Sciences reveal that ground-penetrating radar aboard the rover has identified sedimentary rock layers that strongly suggest the presence of ancient shorelines, painting a picture of a once habitable environment with sun-soaked beaches and gentle waves. Hear the full episode.
The Martian Coastal Landscape
We explore how the radar data reveals a layered structure similar to foreshore deposits found on Earth, indicating a dynamic interface of air and water. This discovery is pivotal as it suggests that Mars was once a much warmer and wetter place than its current arid state, potentially supporting microbial life in its ancient past. The rover's ability to image subsurface geology provides unprecedented insights into Mars' environmental evolution over millions of years.
Implications for Life on Mars
The episode also discusses the significance of these findings in the context of astrobiology. The presence of ancient shorelines raises exciting questions about the potential for life on Mars, particularly in coastal environments where conditions may have been favorable for the development of life. We examine how this new data challenges previous notions of Mars' climatic history and opens up new avenues for exploration and research into the planet's past.
