Study finds early interstellar dust that originated the planets

A recent study conducted by a group of researchers has found some real interstellar dust that is said to have evolved our Earth and our Solar System. According to the study, the interstellar dust dated back to some billions of years ago.

The lead author of the study, Hope Ishii at the University of Hawaii in Manoa, said in a statement the study has discovered some interstellar dust that had originated before the evolution of the Sun and that those interstellar dust proved to be the fundamental building components of stars and planets.

The researchers involved in the study reportedly detected granular particles known as Glass with Embedded Metal and Sulfides (GEMS) that were found to have generated from comets. When these comets pass by our Sun, they tend to generate dust, which reaches the orbit of the Earth and settle down in the atmosphere. In accordance with the researchers, tiny granular components of carbon, various types of ice, and amorphous silicate formed the fundamental building assets of our Solar System. These dust particles, over long time periods, turned into various planetary bodies that scientists study today.

The co-author of the study, James Cliston at the Lawrence Berkeley National Laboratory in California, said in a statement, “These interplanetary dust particles survived from the time before the formation of the planetary bodies in the solar system, and provide insight into the chemistry of those ancient building blocks.”

These ancient interstellar dust were collected by the researchers from the upper atmosphere of our Earth and then studied by using electron microscopes.

Ishii stated, “If we have at our fingertips the starting materials of planet formation from 4.6 billion years ago, that is thrilling and makes possible a deeper understanding of the processes that formed and have since altered them.”

Referring to this latest discovery, astrophysicist Ethan Siegel said in a statement that the findings of the study are indeed a huge discovery. Siegel further said, “If the conclusions stand the test of time, we may have just revolutionized our understanding of how all planetary systems come into being.”
