Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
The Sun is constantly throwing tiny charged particles at us, like a slow invisible wind. Earth's magnetic field deflects most of it, very politely. But near the north and south poles, some of that wind gets through and slams into the air. The air glows. Green from oxygen low down, pink-red from oxygen higher up, blue from nitrogen, all dancing across the sky like the planet is having a quiet, gorgeous tantrum. You're watching our magnetic shield do its job in real time. Thanks, magnetic field.
§ Strange but true
- 01The universe is stranger than your intuition. This is a rule, not an exception.
- 02Every fact in physics was once an outrageous guess. Most still feel like one.
- 03If it doesn't bend your brain a little, you haven't read it carefully enough.
