Earth Sea Star, forever chasing the light
Earth’s star glows in the Orion Arm of the Milky Way. Within a long human lifetime of 81 light years, there are 2600 known stars, with up to another 5000 still unknown.

The Sun is the reason for everything. It provides all light, all power, all direction.
As a photographer, I have switched from looking for subjects in the landscape into chasing the light. Sun sparkle on water, rainbows in a seashell, cloud shadows on the sea. I look for the way a tree beams back at the Sun, or a breaking wave turns translucent with the oblique angle of sunset.
