Vor 1.300 Jahren ist der Osten des heutigen Deutschlands zwischen Elbe und Oder fast menschenleer. Doch dann betreten Fremde aus dem Osten, Slawen, das fruchtbare Land. Sie lassen sich im 7. Jahrhundert nach Christus nieder. Wer war dieses Volk, das überall in Ost- und Süd-Europa Spuren hinterließ?
Sie zählen später zu den letzten Heiden in der Mitte Europas und haben eine bis heute geheimnisvolle Geschichte, in der viele Fragen offen sind und viel Raum für Sagen und Mythen bleibt. Sie verteidigen sich gegen mächtige Gegner und prägen das Mittelalter zwischen Elbe und Oder mit ihrer ländlichen Kultur und ihrem Glauben an Naturgötter. Es sind keine Könige und Kaiser, sondern Bauern und Handwerker; sie gründen nie einen eigenen Staat und haben dennoch die heutigen Nationen entscheidend geprägt.
Die slawischen Vorfahren haben über die Jahrhunderte zur Entwicklung der Zivilgesellschaften des heutigen Europas beigetragen. Seit dem 7. Jahrhundert lassen sich slawische Stämme nachweisen, gibt es Zeugnisse kriegerischer Auseinandersetzungen und heidnischer Gottesanbetungen. Wie haben sich die Slawen ohne feste Landesgrenzen über Jahrhunderte entwickeln, ihre Bräuche, Religionen und Kulturen pflegen und vieles davon letztlich bis heute bewahren können?
Die Dokumentation begleitet eine Gruppe von Slawen zwischen Elbe und Oder durch die Jahrhunderte, folgt ihnen in diverse Scharmützel, beobachtet ihre Bräuche und Riten und zeiget ihr Überlebensgeschick und ihren Kampf um eine eigene Identität vor dem Hintergrund großer historischer Umbrüche.
Imagine you are flying above the African savannah, swimming under Antarctic ice, climbing up Amazon trees and diving the Marianna abyss.
Imagine you can suddenly see in the night, hear ultra-sounds, decode radar waves and detect electric fields.
1,2,3… you are a lion or else a dolphin, a bear or a vulture!
Using the latest technologies of image treatment and stock footage from Saint Thomas Productions’ extensive film library, this wildlife series presents an insider’s view of the predators’ life and senses. Both spectacular and entertaining, the series gives a modern outlook on nature and its most spectacular ambassadors: predators.
Each episode depicts a predator and its hunting techniques in its natural habitat. Following the principles of a food chain, the programmes jump from one animal to the next, from hunter to prey.
Poles
Mirages are shaping over the immaculate ice shelf. Close up shot of a bear inhaling the frozen air. From the bear’s point of view, we understand that… he is smelling a seal. This odour is that of a young ringed seal hidden under a thin layer of snow. A few steps and paw swipes to clear the animal and uncover a young ringed seal snack. Under the ice shelf, protected from bears by several meters of frozen ice, belugas- the white whales- are hunting halibut. In their tridimensional environment, individuals can communicate the good hunting spots while kilometres apart. The chattering of these ghost hunters is continuous. At the South Pole, leopard seals hunt in silence. But they are nonetheless excellent tacticians. Their hunt is based on their excellent sight, experience and a perfect knowledge of their prey’s calendar. When do the parent penguins go off to feed at sea, when do they return, when are the young going to take their first bath and where exactly will they get into the water? The answers to these questions are all part of the leopard seal’s hunting culture. We follow his adventures under the surface of ice-covered bays. When his hunting season comes to an end at fall, the Northern spring wakes the polar bear which goes off to hunt. Our year in the lives of Pole predators comes to a close.

Around the Crozet Islands, here is the incredible odyssey of a family of Sperm Whales facing rapid changes in their environment. From the stormy surface to the eternal darkness of the abyss, several generations of these deep-sea divers encounter men and their «toys»: harpoons of yesterday, and fishing lines of today. Once victim of whale hunting, now accused of stealing fish, a sperm whale shares its private life with us. And what an immersion! We discover in turn its mysterious sonar, its competitors like orcas, and also the strange world of its neighbors — the deep-sea monsters. Amongst them, a revelation: the biggest squid ever filmed in its natural environment, almost 15 feet long. Come and discover the depths of the Crozet abyss…

Процесс настройки расположения всех оптических элементов телескопа на одной оптической оси называется юстировкой. В этом видео мы расскажем о юстировке телескопа-рефлектора системы Ньютона. Такие телескопы очень популярны и хорошо настроенный инструмент с качественной оптикой способен обеспечить первоклассную картинку в хорошую ночь. Ничего сложного в процессе настройки нет и справиться с этой задачей вполне под силу каждому, кто не поленился во всём разобраться.

Stunning imagery illustrates Hubble Space Telescope part in a global scientific effort to understand how stars explode, what effect they have on the universe, and what they can tell us about its origins and future. From Hubblecast.
Most stars in the Universe are small and insignificant, like our Sun They eventually fizzle and die without much drama. But a few light up the sky when they die, and in the process, they dont just tell us about the lives of stars: they create the building blocks of life, and help us to unravel the whole history of the Universe. These are the stars that end their lives as supernovae, explosions that are among the most violent events in the Universe.
