"So tired and I couldn't even sleep..."

Soul Asylum

A picture is worth a thousand words... Pictures capture our best and our worst. Raw emotion. Unspeakable beauty. From the grandeur of nature to the synthetic perfection of everything man-made, pictures communicate to us. Sometimes they whisper a quiet, peaceful message that uplifts our soul. Sometimes they scream at us with impassioned joy or heated rage.

The beauty of the internet is that there are millions of these incredible communiqués at the click of a button. This blog is devoted to these glossy images and everything they stand for.Every post will be categorized in some fashion or another by a theme. For instance, top 10 pictures of cars, top 10 pictures of guitars, top 10 pictures of sunsets, etc.

Today's Post: Night time. When we are all supposed to be asleep. Or are we? Why would the wee hours of the morning be so beautiful if we aren't meant to enjoi? So from sunset to sunrise these are the top ten night pictures.

And now, a little wiki-spective about night. (don't ya just love wikipedia?)

Nights are shorter than days on average due to two factors. One, the sun is not a point, but has an apparent size of about 32 minutes of arc. Two, the atmosphere refracts sunlight so that some of it reaches the ground when the sun is below the horizon by about 34 minutes of arc. The combination of these two factors means that light reaches the ground when the centre of the sun is below the horizon by about 50 minutes of arc.
Without these effects, day and night would be the same length at the autumnal (autumn/fall) and vernal (spring) equinoxes, the moments when the sun passes over the equator. In reality, around the equinoxes the day is almost 14 minutes longer than the night at the equator, and even more closer to the poles. The summer and winter solstices mark the shortest night and the longest night, respectively.

Nótt, the Norse goddess of the night, rides her horse in this 19th century painting by Peter Nicolai Arbo.
The closer a location is to the North or South Pole, the larger the range of variation in the night's length. Although equinoxes occur with a day and night close to equal length, before and after an equinox the ratio of night to day changes more rapidly in locations near the poles than in locations between the Tropic of Cancer and the Tropic of Capricorn. In the Northern Hemisphere, Denmark has shorter nights in June than India has. In the Southern Hemisphere, Antarctica has longer nights in June than Chile has. The Northern and Southern Hemispheres of the world experience the same patterns of night length at the same latitudes, but the cycles are 6 months apart so that one hemisphere experiences long nights (winter) while the other is experiencing short nights (summer).
Between the pole and the polar circle, the variation in daylight hours is so extreme that for a portion of the summer, there is no longer an intervening night between consecutive days and in the winter there is a period that there is no intervening day between consecutive nights.

Thanks wikipedia... but I still think the pictures did a better job!!!
