Why Does The Sky Turn Colors During Sunset?

Tools

By By Steve Pool

SEATTLE - When the sun is low in the horizon, the sunlight has to travel through more particles in the atmosphere.

You see sunlight as white, but it's made up as a combination of the colors of the spectrum.

Those particles will tend to scatter away the blue and green light part of the sunlight's spectrum, leaving behind the more-difficult-to-scatter red and

orange colors. That's because red and orange lights has a longer wavelength than the blue and greens, making it less affected by particles.

Pollution, ash or smoke can enhance the colors as there's more particles to scatter away the shorter-wavelength part of the spectrum.

When I saw this dramatic cloud to the north, it reminded me of smoke, rising in billows until it hits the jet stream, then it's pulled hundreds of miles east. I had to capture it quickly. Within minutes the effect had faded.

For my girlfriends birthday we had a party at her parents. We knew the nest was there but the owner hadn't seen or heard the osprey for a day or two. He asked me to fly my drone up and see if any was wrong. I flew up and found that there were two eggs inside.

The secret to this garden is simple.
I used recycled grass clippings.
