Space Nuts Episode 474 Q&A: Cosmic Constellations, Comet Mysteries, and Citizen Science
Join Andrew Dunkley and Professor Fred Watson as they explore the wonders of the universe in this Q&A edition of Space Nuts. From the shifting constellations as you journey through Space to the enigmatic nature of comets and the age of the universe, this episode is packed with celestial insights and intriguing questions from our audience.
Episode Highlights:
- Constellations from Afar: Discover how the constellations we know would appear from different vantage points in Space. How far must you travel before the familiar star patterns become unrecognisable?
- Comet Tsuchinshan-ATLAS: Delve into the story of Comet Tsuchinshan-ATLAS, its recent appearance in our skies, and the question of whether it has visited our solar system before. Learn about the signs that indicate a comet's history and its journey from the Oort Cloud.
- Age of the Universe: Uncover the methods used to determine the age of the universe, including the role of the Hubble constant and the importance of measuring cosmic distances. How close are we to knowing the exact age?
