Origin of life on Earth through iron particles from meteorites as catalyst

https://www.mpg.de/20330250/0522-astr-iron-life-earth-150980-x

Researchers from the Max Planck Institute for Astronomy and the Ludwig Maximilian University of Munich have proposed a new scenario for the emergence of the first building blocks of life on Earth around 4 billion years ago. With the help of experiments, they recreate the conditions of Earth’s primordial atmosphere and show how iron particles from meteorites and volcanic ash could have acted as catalysts to convert the carbon dioxide-rich atmosphere into hydrocarbons, as well as acetaldehyde and formaldehyde. These substances are the building blocks for organic molecules such as fatty acids, nucleobases (building blocks of DNA), sugars and amino acids, which in turn are the basic building blocks of life.

Reconstructing alien astronomers’ view of our home galaxy’s chemistry

https://www.mpg.de/20470314/reconstructing-alien-astronomers-view-of-our-home-galaxy-s-chemistry

Researchers have reconstructed what alien astronomers, observing our Milky Way galaxy from afar, would find if they analysed our home galaxy’s chemical composition. The study, which is led by researchers from the Max Planck Institute for Astronomy, is relevant for our own understanding of the cosmos.

Moon dust is not to be sneezed at

https://www.mpg.de/13695263/moon-dust-is-not-to-be-sneezed-at?c=12641423

When the astronauts of the Apollo 11 mission returned to Earth, they had almost 22 kilograms of rock from the surface of the moon in their baggage. Josef Zähringer from the Max Planck Institute for Nuclear Physics in Heidelberg was one of the first researchers allowed to analyze the material in the US. Two months later, Heinrich Wänke’s team at the Max Planck Institute for Chemistry in Mainz also received a grain.

Comet cultural history

The sight of a bright comet has fascinated people at all times. But what is behind such a celestial spectacle? It was only in modern times that researchers discovered the phenomenon – by which time the tail stars had already had a long career as bringers of bad luck or divine messengers.
Halley died in 1742 and so did not live to see his triumph of celestial mechanics
