I like astronomy, archaeology, photography, music and drinking a lot of tea. I hate politics. Something that annoys me: that I shall not respect the permanence, and to take me by what I'm not. The best sign: VIRGO. The worst: the health. The best: adapt and know how to get ahead.

JOURNEY TO THE TWILIGHT Taken by Bill Metallinos on May 7, 2016 @ Corfu, Greece
Journey to the Twilight
Twilight at lagoon Korission , a Natura2.000 area, with the light of Dawn shining above it.
With Constellations still shine in the firmament, the constellation of Cassiopeia shines on the left in the picture.
While to the center distinguish several stars from the constellation of Pegasus, the winged horse of Greek mythology with Perseus and Valerofontis have managed to ride it.
Simultaneously to the right the constellation of Ganymedes, the water bearer of the gods and to the edge of the picture the goat-footed god Pan, with the stars Deneb Algiedi witch in Arabic means the Tail of the Goat, name course adopted by the Almagest of Ptolemy and just right of the star Nashira, which means the lucky one or the one who brings good news.
Now what we see? and why are stars in the light of the sun? What is Twilight?
I quote from Wikipedia
Twilight is the illumination of the Earths lower atmosphere when the Sun itself is not directly visible because it is below the horizon. Twilight is produced by sunlight scattering in the upper atmosphere, illuminating the lower atmosphere so that the surface of the Earth is neither completely lit nor completely dark. The word twilight is also used to denote the periods of time when this illumination occurs.
The further the Sun is below the horizon, the dimmer the twilight (other things such as atmospheric conditions being equal). When the Sun reaches 18 degrees below the horizon, the twilights brightness is nearly zero, and evening twilight becomes nighttime. When the Sun again reaches 18 degrees below the horizon, nighttime becomes morning twilight. Owing to its distinctive quality, primarily the absence of shadows and the appearance of objects silhouetted against the bright sky, twilight has long been popular with photographers, who refer to it as sweet light, and painters, who refer to it as the blue hour, after the French expression: lheure bleue.
