Summary
| Description |
English: Interstellar comet 3I/ATLAS photographed by the 8.2-meter Gemini South telescope on 27 August 2025 during 23:55-23:57 UTC. This is a median stack of two 30-second exposures; the combination of these images helps make the comet appear more clearly by reducing the visibility of image noise and cosmic rays. 3I/ATLAS appears as a bright fuzzy blob at the center, with a faint diffuse tail protruding from the left of the comet (away from the Sun). The image is oriented North up and East left. |
