As you watch the Aurora this evening, it’s worth reflecting that you’re getting a rare direct glimpse of the power of Nature. Those charged particles causing the atmosphere to glow came from a sunspot complex 17 times the diameter of Earth and traveled across 90 million miles at a million miles an hour. Without our magnetic field to protect us, our atmosphere would have been lost to space long ago. Those colours in the sky are Nature reminding us that we’re very lucky to be here amidst the violence. And perhaps therefore also reminding us not to shite it all up :-)
