Old houses in France

  • 28/01/2018

The preservation of historic buildings is a one-way street. There is no chance to renovate or to save a historic site once it’s gone. And we can never be certain what will be valued in the future. This reality brings to light the importance of locating and saving buildings of historic significance―because once a piece of history is destroyed, it is lost forever.

Charlie Waite – 1949

  • 14/12/2017

Waite is an award-winning English landscape photographer. His images have a painterly impression in their use of light and shade.

“A landscape image cuts across all political and national boundaries, it transcends the constraints of language and culture.”

First snow; the winter is here

Snow makes whiteness where it falls,
The bushes look like popcorn balls.
The places where I always play,
Look like somewhere else today.

Black forest

  • 03/12/2017

The Black Forest stretches from the High Rhine in the south to the Kraichgau in the north. In the west it is bounded by the Upper Rhine Plain (which, from a natural region perspective, also includes the low chain of foothills); in the east it transitions to the Gäu, Baar and hill country west of the Klettgau. The Black Forest is the highest part of the South German Scarplands and much of it is densely wooded, a fragment of the Hercynian Forest of Antiquity. It lies upon rocks of the crystalline basement and Bunter Sandstone, and its natural boundary with the surrounding landscapes is formed by the emergence of muschelkalk, which is absent from the Black Forest bedrock.

Thanks to the fertility of the soil which is dependent on the underlying rock, this line is both a vegetation boundary as well as the border between the Altsiedelland (“old settlement land”) and the Black Forest, which was not permanently settled until the High Middle Ages. From north to south the Black Forest extends for over 160 km, attaining a width of up to 50 kilometres in the south, and up to 30 kilometres in the north. Tectonically the range forms a lifted fault block, which rises prominently in the west from the Upper Rhine Plain, whilst seen from the east it has the appearance of a heavily forested plateau.

Cygnus constellation

  • 15/10/2017

Cygnus is a northern constellation lying on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. The swan is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism known as the Northern Cross (in contrast to the Southern Cross). Cygnus was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations.

Cygnus contains Deneb, one of the brightest stars in the night sky and one corner of the Summer Triangle, as well as some notable X-ray sources and the giant stellar association of Cygnus OB2. Cygnus is also known as the Northern Cross. Deneb is the tail star in the constellation and is the Arabic word for tail. One of the stars of this association, NML Cygni, is one of the largest stars currently known. The constellation is also home to Cygnus X-1, a distant X-ray binary containing a supergiant and unseen massive companion that was the first object widely held to be a black hole. Many star systems in Cygnus have known planets as a result of the Kepler Mission observing one patch of the sky, an area around Cygnus. In addition, most of the eastern part of Cygnus is dominated by the Hercules–Corona Borealis Great Wall, a giant galaxy filament that is the largest known structure in the observable universe, covering most of the northern sky.

 

Cygnus constellation

Cygnus is a prominent constellation in the northern sky. Its name means “the swan” in Latin, and it is also known as the Swan constellation.

Cygnus is associated with the myth of Zeus and Leda in Greek mythology. The constellation is easy to find in the sky as it features a well-known asterism known as the Northern Cross. Cygnus was first catalogued the by Greek astronomer Ptolemy in the 2nd century.

Notable objects in the constellation include Cygnus X-1, a famous x-ray source, the bright stars Deneb and Albireo, the Fireworks Galaxy (NGC 6946), and several well-known nebulae: the Pelican Nebula (IC 5070), the North America Nebula (NGC 7000), the Crescent Nebula (NGC 6888), and the Veil Nebula (NGC 6960, 6962, 6979, 6992, and 6995).

Cygnus is the 16th largest constellation in the night sky, occupying an area of 804 square degrees. It lies in the fourth quadrant of the northern hemisphere (NQ4) and can be seen at latitudes between +90° and -40°. The neighboring constellations are Cepheus, Draco, Lacerta, Lyra, Pegasus, and Vulpecula.

Cygnus belongs to the Hercules family of constellations, along with Aquila, Ara, Centaurus, Corona Australis, Corvus, Crater, Crux, Hercules, Hydra, Lupus, Lyra, Ophiuchus, Sagitta, Scutum, Sextans, Serpens, Triangulum Australe, and Vulpecula.

Cygnus has 10 stars with known planets and contains two Messier objects: Messier 29 (NGC 6913) and Messier 39 (NGC 7092). The brightest star in the constellation is Deneb, Alpha Cygni, which is also the 19th brightest star in the sky, with an apparent magnitude of 1.25. There are two meteor showers associated with the constellation: the October Cygnids and the Kappa Cygnids.
