Radio Scintillation Observations of the Plasma Tail of Interstellar Comet 2I/Borisov, by P K Manoharan et al.*
Comet 2I/Borisov was only the second interstellar object known to have entered the solar system. The highly eccentric, hyperbolic orbit of 2I/Borisov and its high inclination to the ecliptic plane demonstrated that the comet had an extrasolar system origin (e.g., Manzini et al. 2020). Polarimetric observations of this comet suggested a remarkably smooth, pristine coma with a high concentration of carbon monoxide, that had likely never interacted with the solar […]
