The European Space Agency's Euclid telescope discovers its first comet

The European Space Agency's (ESA) Euclid space telescope has discovered its first previously unknown comet using images captured between September 16 and 24, 2026. While the mission has previously detected other comets, this marks the first novel discovery of its kind for the telescope.

The ESA has highlighted the finding as particularly impressive given that the observatory was originally designed to capture deep space images rather than specifically hunt for comets.
