Avi Loeb   ∙   June 30, 2026   ∙   3 min read   ∙   View on Medium The inferred emissivity spectrum as a function of wavelength (in micrometers) of the dust shed by the interstellar object 3I/ATLAS, with the best-fit model as a purple dashed line. Model components with non-zero contributions are shown below the spectrum. Part of the 6.9 micrometer feature is not well-captured by the model. (Figure credit: M. Belyakov et al. 2026) In a new paper posted here, Matthew Belyakov (from Caltech) and collaborators present the first spectroscopic mineralogical analysis of the dust shed by the interstellar object 3I/ATLAS. The analysis pertains to mid-infrared spectroscopy of 3I/ATLAS by the Webb telescope. The object exhibited a strong spectral feature at a wavelength of 10-micrometers, implying a dust composition dominated by amorphous silicates. Unlike Solar System comets which show significant crystalline silicate dust, the composition of the dust shed by 3I/ATLAS after perihelion is more similar to the dust in the interstellar medium. … Continue reading Continue reading this story on Medium.
