Our planet’s electronic vulnerability

The Milky Way stretches in a broad arc across a dark, star-filled sky above a mountain range with snow-dusted peaks and green alpine valleys. Bright pink and magenta clouds of glowing gas are visible in the upper left portion of the sky, with patches of dark dust threading through the dense band of stars. A few small structures — including a tiny settlement — are visible at the base of the mountains.
