Kind: research · Impact: low

## In brief

- School groups in Upminster, Bridgend, Alcarràs and Zagreb sent position measurements of an interstellar comet.
- The measurements were sent in the weeks before the Webb Telescope observed the comet on December 22, 2025.
- The positions helped astronomers refine the predicted location of the comet, which reportedly contains unusual chemicals.

## Why it matters

Citizen-science position data from students helped astronomers target a fast-moving interstellar object for follow-up observation, showing how amateur measurements can support professional telescope campaigns.
