The Formation of Stars | NASA Planetary Sciences
Discover how the James Webb Space Telescope will help us better understand solar system formation in this video from NASA. Images from the Hubble Space Telescope show star-forming regions within the Eagle nebula: visible light images show vast clouds of gas and dust, and infrared images provide a gl
The formation of the Alps
The Alps are Central Europe's highest mountains, towering as high as 4800 meters. Today, mainly the harsh weather shapes the Alps. But the forces that formed these mountains came from within the Earth. Author: ZDF/Terra X/Bilderfest/Florian Breier, Christian Stiefenhofer/Michi Kern/Klaus Wache/Tob
Mauvein: The Invention of the First Synthetic Dye
In the mid-19th century, chemical assistant Henry Perkin was looking for an synthetic substitute for an antimalarial drug. But instead of quinine, he produces the first synthetic dye: mauveine. An accidental product! Authors: ZDF/Terra X/T. Schrader/J. Koester/F. Steinhardt/Moods in Pictures/Maximi
08 Salt formation from the elements
Sodium reacts with chlorine to form a white salt, sodium chloride. An ionic bond of cations and anions is formed. It is explained how the PSE helps to determine the charges of the ions and to establish the ratio formula from them. Original: "Wolfgang Dukorn" Original: German. All translations in t
Formation of New Species by Speciation | Evolution | Biology | FuseSchool
In this video you will learn how weird and wonderful animals are formed in the process of speciation and the formation of new species. Different selection pressures select for different characteristics. Over generations, the individuals with the beneficial traits will prosper, and others will die
Formation of the Baltic Sea
20,000 years ago, the Baltic Sea region was still covered by a glacier. A change in climate caused the glacial ice to melt. The first form of the Baltic Sea emerged: a freshwater lake. Today, despite its connection to the North Sea, it is considered an inland sea. Author: ZDF/Terra X/Nina Zorn/Anna
