摘要
| 描述 |
English: Two-frame animation of interstellar comet 3I/ATLAS (big gray fuzzy blob), seen moving across a field of stars in Hubble Space Telescope images taken on 21 July 2025 18:04 and 18:06 UTC. Each frame is a 25-second exposure taken with the WFC3 camera's F350LP filter. The stars appear trailed because the Hubble Space Telescope was following the comet's movement during the image exposure. Stray white pixels and spots that sporadically appear between frames are image artifacts caused by cosmic rays striking Hubble's camera during the exposure. The images are oriented North up, East left. |
