Liquid water found in a meteorite

Water would be very common in the universe. If several scientists have already marked this conclusion, the recent discovery of liquid water in a meteorite would confirm it.

We knew that water was already very present in our solar system, the most visible evidence in the rings of Saturn or on Europe, the famous satellite of Jupiter. However, the recent discovery of water in a meteorite, a fragment of a 4.6 billion year old asteroid, is abundant in the theories that the presence of this element everywhere in our galaxy and even on the scale of the universe promote.

And for once, the discovered water is not in the form of ice, but rather liquid. A prime for a meteorite of this type. Scientists have been looking at the fragments of the Sutter’s meteorite that erupted in 2012 in our atmosphere. Classified under the meteorites called carbonaceous chondrites, so rich in carbon and of which iron is oxidized.

Water from outside Jupiter?

The team of researchers, led by Dr. Akira Tsuchiyama, professor at Ritsumeikan University in Kyoto (Japan), used new techniques in microscopy. And her work has identified small inclusions of water in a microcrystal of calcite hidden in the fragments of this meteorite.

“The inclusions were probably due to the formation of the parent steroid with lumps of frozen water and carbon dioxide in it. This would require the asteroid to be formed in a part of the solar system that is cold enough for water and carbon dioxide to freeze, and these conditions would place the formation site well outside the Earth’s orbit, possibly even outside. Jupiter, ”explained Dr. Akira Tsuchiyama on the university’s website and reports on his research. Before we concluded that we “detected a small fluid that was trapped in a mineral 4.6 billion years ago”, i.e. in the formation of our solar system.
