Can aircraft pollutant emissions be reduced by using biofuels? And what influence does an alternative fuel have on the formation of contrails? In mid-January, a joint German Aerospace Center (DLR) and ...

Researchers have conducted the most complete analysis of the chemical composition and evolutionary state of a spectral type R carbon star. The presence of carbon is essential for the possible ...

The atmosphere is a mixture of gases. The atmosphere is mostly nitrogen (approximately 80%) and oxygen (approximately 20%). The remaining gases are found in much smaller proportions, such as carbon ...

Chemical analysis of some of the world's oldest rocks has provided the earliest record yet of Earth's atmosphere. The results show that the air 4 billion years ago was very similar to that more than a ...

The Earth’s atmosphere is a complex and dynamic envelope comprised primarily of nitrogen and oxygen, with trace gases such as carbon dioxide, methane, water vapour and ozone playing outsized roles in ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Robyn Williams: The Science Show has also been preoccupied in recent times with the ancient Earth, life ...

Compounds emitted by trees, diterpenes, could have a previously unconsidered impact on the formation of particles in the atmosphere. The study by the of the Spanish National Research Council (CSIC) ...

A selection of fossilized micrometeorites recovered from Cretaceous chalk. These particles were initially composed of Fe-Ni metal but during atmospheric entry they oxidized to form Fe-oxide minerals.

Researchers of the University of Granada have conducted the most complete worldwide analysis of the chemical composition and evolutionary state of a spectral type R carbon star The presence of carbon ...
