Fifty years ago, the theory of plate tectonics revolutionized geology. This new conceptual framework made it possible to understand continents and oceans’ formation and the distribution of volcanoes and mountains. Plate tectonics is a model that describes the movement of the cold, rigid layer that forms the Earth’s surface, the lithosphere. In the 1960s, scientists… Continue reading How to See the Movement of a Tectonic Plate From Space
Chocolate has been one of the most consumed products in the world for generations. European countries tend to top the list: in 2017, Switzerland was the largest cocoa consumer per capita, with an average of 8.8 kg consumed per person. In 1995 France launched the initiative to celebrate International Chocolate Day every September 13. The… Continue reading Microorganisms, Chemistry and Chocolate: a Delicious Relationship
Hope in the fight against antibiotic-resistant germs: Researchers have produced an active ingredient from a component of wasp venom that could fight bacterial infections in animal experiments. They have succeeded in eliminating the problematic aspects of the toxic substance for humans while at the same time increasing its effectiveness against bacteria. The candidate for the… Continue reading Antibiotics | Bacteria Eradicator Inspired by Wasp Venom
The “Starlink” project by SpaceX and Elon Musk aims to make high-speed Internet available everywhere. Many satellites are required for this – that is a source of criticism. The private space company SpaceX of Elon Musk wants fast Internet from space For this purpose, thousands of satellites are to be brought into orbit Astronomers have… Continue reading SpaceX’s “Starlink” satellites: This is what’s behind Elon Musk’s project
The potent greenhouse gas methane rises from the sea floor in many oceans. Only Antarctica was not known to have such active methane emissions – this has now changed. In 2011, during a diving expedition along the coast of Ross Island, US researchers discovered the first signs of a freshly formed methane source on the… Continue reading First methane source under Antarctic sea ice
The earth is not alone in space: people have long been observing the sun, moon and stars in the sky. They discovered early on that some stars are moving. These wandering stars were observed and their paths followed. But for a long time their movements were not understood – until about five hundred years ago… Continue reading What is the Solar System?
One of the most beautiful spectacles that exists in our world is the view of the starry sky on a dark moonless night. But what are stars? Do stars shine on their own? Stars and galaxies Dimensions, mass and luminosity of stars Red Dwarfs White Dwarfs Red supergiants The hidden mass of the universe Stars… Continue reading What are Stars? A Short Introduction.
If we don’t hold a glass tight enough in our hands, it will fall. It does not stay in the air and does not fly up, but – unfortunately – always lands on the ground. This is due to the laws of gravitational force: mass bodies attract each other. And because the earth has a… Continue reading Why is gravity important for our lives?
The star LAMOST J040643.69 + 542347.8 is located in the outer arm of the Milky Way. Astrophysicists discovered the fastest spinning star in the Milky Way Galaxy. Its distance of about 30 thousand light years from the Sun, and its upper layers rotate at a record high speed. About 540 kilometers per second, which is… Continue reading Chinese astrophysicists discovered the fastest rotating star of the Milky Way
