Shown at center, this image features Earth’s moon, with the limb of Earth transitioning into the troposphere (orange).
The troposphere is the lowest and densest component of Earth’s atmosphere.
The sharp boundary between the orange and blue regions is the tropopause. Silvery-blue noctilucent clouds can also be seen far above Earth’s troposphere.
