Comet K1, whose full name is Comet C/2025 K1 (ATLAS), had just passed its closest approach to the Sun and was heading out of the Solar System. Though it had been intact just days before, K1 fragmented into at least four pieces while the NASA/ESA Hubble Space Telescope was watching. The odds of that happening while Hubble viewed the comet are extraordinarily miniscule.
Conventional SETI (Search For Extraterrestrial Intelligence) strategies have long been built on the idea that intelligent extraterrestrials (ETI) would aim to communicate with other intelligent civilizations along a very narrow band of the electromagnetic spectrum, preferably in the radio spectrum.
