Earth's Atmosphere
EARTH · the thin blue line
Astronauts describe the same shock: from orbit, our atmosphere is a heartbreakingly thin blue line hugging the planet, like the skin on an apple. That sliver does everything: it shields us from radiation and meteors, carries our weather, traps just enough warmth, and holds every breath ever taken. There is no spare.
