“We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.”
- T.S. Eliot, from “Little Gidding,”

The Glowing North Sea
As sunlight and warmth increase in the spring and summer, the North Sea starts to gain swirls and tendrils of color. Phytoplankton— organisms that often float near the ocean surface—become abundant during this time, giving the shallow water the distinctive.
In astronomy, an analemma is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from fixed location on the Earth. Due to the Earth's axial tilt and orbital eccentricity, Sun will not be in the same position in the sky at the same time every day.
Thunderstorm Seen From the Space Station
Thunderstorms in Earth’s upper atmosphere remain something of a mystery. Scientists cannot reach them directly with instruments; they are too high for balloons.
The space station offers this investigation an ideal observing platform.
