A simple trail of the interstellar dust can take us back to the origin of the solar system. Just like every other star and planet systems of the different galaxies, our solar system started as a cloud of interstellar dust and gas. Some of those pre-solar dust particles are still preserved in certain cosmic objects like the comets and asteroids. Tons of such cosmic specks of dust fall on the Earth’s atmosphere every year. The scientists are following a trail of such interstellar dust to go back in time to discover more details about the formation and transformation of our solar system.
NASA Is Analyzing Such Pre-Solar Cosmic Dust –
NASA uses a special aircraft with a sticky collector to catch the falling interstellar specks of dust onto the Earth’s atmosphere at a very high altitude. The lower the specks of dust come down, they get contaminated by the materials present on our planet. Hope Ishii is leading a team of researchers to study and analyze
