In the vast, icy darkness of interstellar space, a pristine time capsule has been sailing for potentially billions of years, untouched by the stellar nurseries of our Solar System. Astronomers, already stunned by the speed and unique origin of the comet 3I/ATLAS, now face a genuinely mind-bending theory: this interstellar visitor may be erupting with active, icy cryovolcanoes.
If confirmed, the evidence detailed in a new pre-print study doesn't just add a colourful footnote to the comet's story; it forces a profound reconsideration of how comets—not only those from distant star systems but those in our own cosmic backyard—are formed.
