Feature Guest: Sabine Stanley
Professor Sabine Stanley joins Justin Trottier at The Star Spot to discuss everything to do with magnetic fields: how they’re created, where they can be found, and what they tell us about the composition and behaviour of planets. Why does Mercury have a magnetic field when we originally predicted it shouldn’t? Why does Saturn’s magnetic field line up so perfectly with its geographic poles? What makes the magnetic field of Mars so different in its northern and southern hemispheres?
The two then focus on Earth’s magnetic field which is known to flip north and south poles throughout its history. Why do flips happen? Why do they occur at seemingly irregular intervals? Are they dangerous to life? Dr. Stanley shares her excitement for how using mangetic fields as another tool in searching for habitable exoplanets. Finally the two discuss upcoming missions to study the magnetic fields of objects in our solar system, such as the Jupiter Icy Moons Explorer (JUICE) which will use mgnetic field information to tell us more about the oceans under Europa’s ice sheets.
