Euclid, a telescope built to survey 1.5 billion distant galaxies, has found its first comet, C/2026 S1 (Euclid), about 1.3 billion km away. New software from Mikko Pöntinen flagged a streak across several images, and the comet's odd orbit arching over the galaxy carried it through one of Euclid's fields.
