This webinar delves into the fascinating world of extraterrestrial materials characterization at the sub-micrometer scale.
Our Solar System formed 4.6 billion years ago from the collapse of an interstellar dust and gas cloud. While most of this material was transformed during planetary formation, a tiny fraction survived intact. These ancient grains, found today in meteorites, interplanetary dust, and cometary matter, carry the isotopic signatures of their parent stars, offering a direct window into stellar processes.
Discover how NanoSIMS enables scientists to analyze these “stardust” grains with unparalleled resolution, revealing insights into stellar nucleosynthesis, dust formation around red giant stars, novae, and supernovae, and into the chemical evolution of our galaxy.
