Space Nuts Episode 491: The Windiest Planet, Martian Mysteries, and Light Pollution Concerns
Join Andrew Dunkley and Professor Jonti Horner in this captivating episode of Space Nuts, where they explore some of the most fascinating cosmic discoveries of our time. From the extraordinary winds of a distant exoplanet to intriguing geological findings on Mars, and the looming threat of light pollution on astronomical observations, this episode is packed with insights that will expand your cosmic perspective.
Episode Highlights:
- The Windiest Planet: Discover Wasp 127B, the exoplanet with astonishing wind speeds reaching up to 33,000 kilometers per hour. Andrew and Jonti delve into the implications of these extreme weather conditions and what they reveal about the planet's atmosphere and energy dynamics.
- Martian Terrain Discovery: A new study uncovers a fascinating area on Mars that suggests the presence of permanent liquid water in the planet's ancient past. Jonti explains the significance of the clay deposits found in the northern lowlands and how they relate to the theory of a Martian ocean.
- Protostar Insights: Learn about T Tauri North, a protostar set to fade from view as it moves behind a thick disk of material in a triple star system. Andrew and Jonti discuss the scientific opportunities this presents for studying the formation of stars and planets in such systems.
- Light Pollution Threat: The Extremely Large Telescope, built in one of the darkest places on Earth, faces potential light pollution from a nearby renewable energy project. Explore the challenges this poses to astronomical research and the delicate balance between development and preservation of dark skies.
