An ancient object than the Earth fell into the Sahara, revealing the secret of 'earthquake'

Our oldest homeland may be a snow circle - the beautiful water around the young sun, which provides materials to shape the Earth and its neighbors.

Research led by Earth and planetary scientist Meguma Matsumoto (Kyoto University, Japan) has found a strange thing called "ice fossils" in a meteorite dating back 4.6 billion years. age five, equivalent to the age of the Solar System and "older" than the earth.

The asteroid, named Acfer 094m, fell to Algeria in the Sahara Desert (North Africa) in 1990. Modern analytical tools have helped scientists identify it as a "primitive meteorite". " , the rare and precious remnant of the solar nebula.

The "ice fossils" inside this ancient meteorite shed light on how asteroids formed in the early solar system, then to the asteroids. In other words, the fossil consists of fine silicate dust containing silicate, sulfur and this organic material that represents one of the "planet building blocks" that make up Earth and all other planets. in the Solar System.

According to Matsumoto, the fossil material has a strange structure consisting of a smooth mass of silicate and other materials surrounded by an icy layer of pure water.

It has revealed our home image of our early Solar System. At that time, there was no Earth and other planets. Only a young sun is shining amidst a beautiful icy stream, "flowing" in a closed loop around it. This image has been observed in several other young stars in the universe - the very beginning of the other "Solar System" .

In that past Solar System, swirling dust, gas and even ice condensed, forming rock asteroids or lunar-sized objects, and then planets.

During formation, new objects tend to head towards the sun, causing the ancient ice to belong to the snow ring - the old water began to melt, turning into fossils of ice. Accidentally, ice fossils have "crept" into the cracks of this ancient meteorite, preserved and followed a mysterious path, landed on Earth after billions of years of wandering.

The research has just been published in the scientific journal Science Advances.
