Evidence of (16) Psyche’s Metallic Nature Found with SOFIA

Led by Anicia Arredondo, researchers used the Stratospheric Observatory for Infrared Astronomy (SOFIA) to investigate the metallic nature of the asteroid Psyche, believed to be rich in metals. SOFIA observed the entire surface of Psyche, using mid-infrared instruments to analyze its emissivity and porosity. The results confirmed that Psyche is a metallic body with some differences between the northern and southern poles. This study paves the way for NASA's mission to Psyche, launching in October 2023, promising insights into planetary cores and planet formation. Psyche's size and potential for differentiation make it a significant subject for understanding Earth-like planets. Join Anicia and SETI Institute senior astronomer Franck Marchis to learn more!
