Africa-Press – Mauritius. <\/strong><\/span>A piece of rock from the Red Planet landed on Earth over two centuries ago, and thanks to its unique composition, it made possible a new discovery that could change astronomers\u2019 views regarding the early days of Mars.
\nA recent analysis of the composition of the Chassingy meteorite, which originated from Mars and hit our planet in 1815, revealed that the Red Planet possibly formed its core from different materials than originally thought.
\nScientists previously believed that the core of Mars was formed by the gases of the young Solar System\u2019s nebula, with meteorites bringing in additional volatile elements later.
\nThis assumption was based on an earlier examination of the meteorite, which revealed the presence of xenon \u2013 an inert gas common to nebulas. However, a new study led by the University of California took a fresh look at the two-centuries-old piece of rock:
\nThe new finding suggests that the planet\u2019s core might have been formed mostly as the result of meteorite collisions. At the same time, the planet\u2019s atmosphere was largely made of gases from the solar nebula, whilst previously scientists believed that these gases were pushed out of the nebula-formed core.
\nThe new model also suggests that Mars acquired its first atmosphere after cooling off instead of creating it at the stage when it was a molten piece of rock.
\nThe new research, however, has raised new questions: if Mars\u2019 atmosphere was created out of nebula, why wasn\u2019t it blown off like the nebula itself due to solar radiation? This question remains to be answered if the findings of the scientists from the University of California stand confirmed after peer review of their work.<\/p>\n
