Scientists have revealed that some of Earth’s atmosphere may have been brought to the planet by comets billions of years ago. The mystery of how the Earth’s atmosphere was formed has long baffled scientists. Some researchers think comets might have originally brought some of the water, organic and atmospheric molecules to Earth that now make up its life. Now a new study from The University of Manchester, UK, Centre de Recherches Pétrographiques et Géochimiques (CRPG) and Université de Lorraine (Nancy, France), has found evidence to back up the theory.
The scientists have been analysing tiny samples of ancient air trapped in water bubbles found in quartz, which dates back >3 b...
