Why Is June 21 The Longest Day Of The Year?

SEATTLE - The Earth tilts on an axis as it orbits around the sun.

In the Northern Hemisphere, June 21 is the day when we are tilted closest to the sun -- thus the sun appears highest in the sky (about 66 degrees above the horizon at noon for Seattle). That means the sun spends the most amount of time above the horizon that day.

It's exactly opposite in the Southern Hemisphere, where the Earth is tilted furthest away from the sun, so for them, today's the first day of winter. So while we're in shorts, Australians are bundling up.

It works the opposite for winter on Dec. 21. That's when we're tilted furthest away from the sun, and get the shortest day of the year.

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.
