When we witness the Northern Lights dancing across the sky, we're seeing the visible aftermath of explosions that release more energy than billions of nuclear bombs. The Sun fuses 600 million tons of hydrogen into helium every second, occasionally blasting billions of tons of charged particles toward Earth in Coronal Mass Ejections that can cross 93 million miles in as little as 15-18 hours. These cosmic hurricanes create auroras when they funnel through Earth's magnetic field lines and excite atmospheric gases, producing those vivid greens from oxygen and blues and purples from nitrogen.

But this celestial beauty comes with serious risks. The same solar energy that creates stunning auroras can overload our technological infrastructure. The 1989 Quebec blackout left six million people in darkness for nine hours, and researchers estimate a Carrington Event-level storm today could cause $2.6 trillion in global damage. We came terrifyingly close in July 2012 when a massive solar eruption narrowly missed Earth—one that scientists believe was at least as strong as the infamous 1859 event.

In today's tech news, we examine Bluetooth 6.2's protection against sophisticated RF attacks that manipulate signal amplitude to fool proximity systems, YouTube's platform changes forcing yt-dlp to require external JavaScript runtimes, and FFmpeg developers' frustration with Google using AI to find bugs in volunteer-maintained critical infrastructure without adequate funding. We also look at the disappearing art of laptop sticker culture and the Network Time Foundation's funding challenges.
