Space Nuts #472 Q&A Edition: Titan's Mysteries and Cosmic Curiosities Join Andrew Dunkley and Professor Fred Watson in this intriguing Q&A episode of Space Nuts, where they delve into the mysteries of our solar system and beyond, addressing questions from their curious audience. From the unique atmosphere of Titan to the hypothetical existence of Planet Nine, this episode is filled with captivating discussions and astronomical insights. Episode Highlights: - Titan's Atmospheric Enigma: Explore the origins of Titan's thick nitrogen atmosphere and its ability to retain it, unlike Mars. Discover the role of comets and organic chemistry in shaping this unique moon's environment. - Tidal Locking Explained: Understand the gravitational phenomenon of tidal locking and why proximity and size matter. Learn about the differences in how natural and man-made satellites maintain their orientation. - Planet Nine Hypothesis: Dive into a speculative theory about Planet Nine and its potential impact on Uranus and Mercury. Discuss the ongoing search for this elusive celestial body. - Triton's Dwarf Planet Status: Uncover the history of Neptune's moon Triton and its possible past as a dwarf planet. Examine the characteristics that make Triton a fascinating world in its own right. - Distinguishing Doppler Effects: Differentiate between Doppler shifts caused by relative motion and the redshift due to the universe's expansion. Explore how these phenomena are used to study cosmic objects. For more Space Nuts, including our continually updating newsfeed and to listen to all our episodes, visit our website.
