21 APR 2025 · Unlocking Stellar Secrets in Messier 67: The Role of Stellar Seismology
In this episode of SpaceTime, we dive into the remarkable findings from the study of the open star cluster Messier 67, where astronomers have employed stellar seismology to unravel the evolutionary history of its stars. Located approximately 2,700 light years away, Messier 67 is a treasure trove of information, containing around 500 stars, including white dwarfs and sun-like stars, all born from the same molecular gas cloud about 4 billion years ago. This unique cluster provides a valuable perspective on stellar evolution and the dynamics of our galaxy.
Stellar Seismology: A New Tool for Understanding Star Ages
Lead author Claudia Reyes from the University of New South Wales explains how the study utilized oscillation frequencies of stars to determine their ages—a challenging task in astronomy. By analyzing how stars vibrate, researchers can infer critical details about their internal structure and evolutionary processes. This innovative method not only enhances our understanding of individual stars but also offers insights into the formation and evolution of galaxies, including our own Milky Way.
Implications for Our Sun's Future
The implications of this research extend to the future of our own Sun. As stars evolve, they undergo significant changes, and understanding these processes in Messier 67 helps scientists predict what will happen as our Sun ages. Reyes discusses the fascinating concept of "starquakes," which are akin to earthquakes but occur within stars, providing further insights into stellar dynamics.

Innovative Techniques in Dark Matter Research: Atomic Clocks and Cavity-Stabilized Lasers
In this episode of SpaceTime, we explore a groundbreaking approach to uncovering the mysteries of dark matter through the innovative use of atomic clocks and cavity-stabilized lasers. Dark matter, which constitutes about 80% of the universe's mass, remains largely elusive, and scientists are still striving to understand its true nature. We discuss insights from Ashlee Caddell of the University of Queensland, who explains how her team's research leverages ultra-stable lasers and atomic clocks to detect subtle changes that could indicate the presence of dark matter acting as a wave.
Understanding Dark Matter Through Oscillations
Caddell elaborates on how the unique properties of dark matter lead to oscillations that could be measured by comparing the ticking rates of separated atomic clocks. This method allows researchers to probe previously invisible forms of dark matter that do not emit light or energy. We examine the implications of these findings for our understanding of the universe and the potential to explore a broader range of dark matter scenarios.
Challenges in Dark Matter Detection
The discussion also touches on the historical context of dark matter research, including the challenges faced in detecting weakly interacting massive particles (WIMPs) and the emergence of alternative theories such as axions. Caddell shares her insights on the creative approaches scientists are taking in the ongoing quest to identify and understand dark matter's role in cosmic structures.

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.
