A new study has revealed that the scientists have discovered some of the original interstellar dust which was helped in forming the Earth and the Solar system which are formed billions of years ago.
As per the lead author of the study, Hope Ishli who is from the University of Hawaii at Manoa has said that the discovery is the surviving of the pre-solar interstellar dust and that has formed in every building blocks of planets and stars. The researchers have collected the surviving of ancient dust which is from the Earth’s upper atmosphere, and it is likely to deposit from the Comets. When comets pass near the sun, they release the dust and it can then reach the orbit of the Earth and can settle through the atmosphere. This can be collected and then put into the study with the help of the microscope.
The co-author of the study, James Clinton who is from the Lawrence Berkeley National Laboratory in California has said that these interplanetary dust particles can be survived from the time and it is before the formation of the planetary bodies in the solar system, and it provides the insight into the chemistry of those ancient building rocks. This dust is said to be actually like tiny glassy grains, and they are known as GEMS or glass which are embedded with metal and sulfides, and they are typically less than 1/100th the thickness of the human hair.
The astrophysicist, Ethan Siegel, has referred this study to understand how the planets are formed. He said that the naïve picture of the disk is usually very hot, cool and it fragments them to form the planets, and it may be hopelessly oversimplified. We have learned that it may be cold and the outer material can hold the key to the planetary backyard. Seigel was not the part of the research, but he managed to write about the study in Forbes.
The lead author of the study Siegel said that if we try to do at our fingertips, then we must start materials of the planet formation which are about 4.6 billion years ago.
