Quote:How often does a CME from our sun strike a comet from interstellar space? Almost never--so today’s collision is worth watching. According to a NASA forecast model, a CME launched on Sept. 19th will reach Comet 3I/ATLAS on Sept. 24th or 25th. CMEs hitting Solar System comets have been known to kink or even disconnect their tails. What happens to an interstellar comet is anyone’s guess.
