Summer Is:
- Water Skiing
- Blowing Bubbles
- The Zoo
Camping
The first day of summer officially kicks off today at 7:28 a.m. ET, the beginning of the summer solstice and the longest day of the year—at least in the Northern Hemisphere.
The summer solstice is a result of the Earth's north-south axis being tilted 23.5 degrees relative to the sun. The tilt causes different amounts of sunlight to reach different regions of the planet.
Today the North Pole is tipped closer to the sun than on any other day of 2010. As high noon on the first day of summer, the sun appears at its highest point in the sky—its most directly overhead position—in the Northern Hemisphere.
That doesn't mean the sun will be exactly overhead at noon for everyone, said James Bell, an astronomer at Cornell University in New York State.
It depends on the viewer's latitude—the sun is only shining down directly overhead at noon at the Tropic of Cancer. "It's still at a low angle if you're up in Alaska," Bell explained.

Very interesting. I was told when we are in Scotland in August it doesn't get completely dark. Now I gotta figure out why that is. Is it more north?
ReplyDeletethis is exactly what we studied during our online mystery class! how many hours of daylight certain places get during the spring solstice
