Presolar Dust Grains—Chemistry Begins
Lecture no. 5 from the course: The Origin and Evolution of Earth: From the Big Bang to the Future of Human Existence
Taught by Professor Robert M. Hazen | 32 min | Categories: The Great Courses Plus Online Science Course
Unravel the story told in “presolar” grains of dust formed by stars very different from our sun. These are the earliest building blocks of our own solar system. Learn how scientists identify these microscopic particles, which often contain diamond crystals. Also see how the field of cosmochemistry is revolutionizing the study of minerals.
