Hubble Space Telescope Observations of the Interstellar Interloper 3I/ATLAS: #Interstellar Comet, Hubble Makes Size Estimate: https://science.nasa.gov/missions/hubble/as-nasa-missions-study-interstellar-comet-hubble-makes-size-estimate/ and https://www.esa.int/ESA_Multimedia/Images/2025/08/Hubble_sizes_up_rare_interstellar_comet (which is 5.6 km > nucleus diameter > 320 m, so we still don't know much here).

A comet the size of a small city... just passing by our neighborhood onto the next solar system in a few million years.

The #interstellar #comet #ATLAS with a 2-meter telescope, from the AT "Deep g'-band Imaging of Interstellar Comet 3I/ATLAS from the Two-meter Twin Telescope (TTT)" https://www.astronomerstelegram.org/?read=17264 - other observations were reported in https://www.astronomerstelegram.org/?read=17263 ("Interstellar Interloper C/2025 N1 is Active"), and there are a short JPL video at https://www.youtube.com/watch?v=-vzafaw0t08 and ESA and NASA press releases in https://www.esa.int/Space_Safety/Planetary_Defence/ESA_tracks_rare_interstellar_comet and https://science.nasa.gov/blogs/planetary-defense/2025/07/02/nasa-discovers-interstellar-comet-moving-through-solar-system/

What a waste of time, money, and (presumably) talent.

A timelapse of #interstellar comet ATLAS in the sky from the VLT: https://www.youtube.com/watch?v=IXJ221XXPvM. And there are already three papers: https://arxiv.org/abs/2507.02757 (Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS), https://arxiv.org/abs/2507.05252 (Interstellar comet 3I/ATLAS: discovery and physical description) and https://arxiv.org/abs/2507.05226 (Initial VLT/MUSE spectroscopy of the interstellar object 3I/ATLAS).

The third #interstellar object - formerly known as #A11pl3Z - has just been named 3I/ATLAS: #comet after all!
