Jan 5, 2021
Did you know space has its own weather? Solar flares and coronal mass ejections can unleash charged particles that influence technology and the environment on Earth. The 2003 Halloween storms showcase the chaos of these solar events and even link back to the historical Carrington Event of 1859, which disrupted telegraph systems. The hosts dive into how solar phenomena create dazzling auroras while posing risks to satellites and electrical infrastructure. Plus, there's a fun twist on fandom with 'Gettycorns,' blending science with light-hearted humor!

Episode notes
Space Weather Origins
- The sun's surface and atmosphere are incredibly active and hot, made of plasma.
- This plasma creates a chaotic, roiling mix of magnetic fields, influencing the particles' behavior.
Solar Cycle and Maximum
- Solar activity follows an 11-year cycle, with magnetic poles switching.
- Within this cycle, a solar maximum occurs, marked by increased activity and sunspots.
Sunspots and Magnetism
- Sunspots appear as dark areas on the sun, relatively cooler due to strong magnetic fields.
- Despite appearing dark, they are still extremely hot and bright, about ten times brighter than a full moon.
