Can interstellar dust create the Solar System?

The team of astronomers found some interstellar dust, involved in forming Earth and the Solar System billions of years ago, a new study published in the Astronomical Notice of the British National Academy of Sciences. .

The newly discovered interstellar dust is important because it is the first type of dust to exist before forming the Solar System, planets and stars.

Later, many ancient comets passed near the Sun, releasing dust that could reach the Earth's orbit, and settle down through the atmosphere. Since then, dust can be collected and studied by electron microscopy. That's how the research team analyzed new dust in this study.

"These dust particles are in ancient planetary comets, which existed from time before the formation of planets in the solar system, and it provides insight into the chemical composition of building blocks. the universe was primitive, " said study co-author James Cliston, a researcher at Lawrence Berkeley National Laboratory.

This interstellar comet dust contains a lot of glass along with metals and sulfides, also known as GEMS . They are extremely small and have a thickness of less than 1/100 of the thickness of human hair.

This discovery is very important because it changes the current understanding of how different planets form in the Solar System.

It can even completely change our current perception of the universe.

In addition, scientists plan to carry out many more studies, to take a closer look at interstellar dust, as well as to understand the formation of planetary systems, as well as how they exist. scattered throughout the universe.
