Explanation:
Sunrise seen from low Earth orbit can be very
dramatic indeed
(and the authors don't apologize
to Hemingway for
using his title!).
In this breathtaking view from the
space shuttle Endeavor,
the Sun is just visible peaking
over towering anvil-shaped
storm clouds.
The silhouetted cloud tops mark the
upper boundary of the troposphere, the lowest layer
of planet Earth's atmosphere.
Sunlight filtering through suspended dust causes this dense
layer of air to appear red.
In contrast, the blue stripe marks the
stratosphere, the tenuous upper atmosphere, which preferentially
scatters blue light.
