It wasn’t that far away, but this recent discovery that scientists have made is certainly from a long, long time ago. According to a new study which the journal Proceedings of the National Academy of Sciences recently published, experts have recently stumbled upon the interstellar dust that billions of years ago formed the Earth and our solar system. According to Hope Ishii of the University of Hawaii at Manoa, the lead author of the study, what they discovered is the remaining pre-solar interstellar dust that formed the building blocks on which our planet and the solar system established.
The team of experts managed to collect this ancient dust from the upper atmosphere of our planet. Most likely, comets deposited it there over the years. When they pass the sun, they release dust that sometimes can reach our orbit and atmosphere. This is a good thing as the dust can be collected from there and thoroughly analyzed thanks to electron microscopes. Study co-author James Cliston says that these dust particles are as old as time, as they survived through the formation of the planetary bodies in our solar system. They are beyond valuable as they can provide an insight into how these building blocks actually came to be so much time ago.

It’s worth noting that this dust is, in fact, very small glass grains called GEMS. Actually, it’s glass that has been embedded with metal and sulfides. Those are usually less than 1/100th the thickness of a human hair.
Now, thanks to this discovery, experts have started thinking that our idea about how the planets formed might be actually a lot simpler. It was nothing extremely hot that melted and then cooled to form all of these objects. In fact, the material might have been cold from the beginning. All in all, this is a huge discover that withstood the passage of time only to fall in the experts’ hands. Everything is possible from here.
