• A Complex Jet Structure Emanates from 3I/ATLAS After Perihelion

  This morning, at 4.10 Universal Time (UT) on November 8, 2025, the interstellar object 3I/ATLAS showed a complex jet structure. M. Jäger, G. Rhemann and E. Prosperi observed 3I/ATLAS at 29 degrees separation from the Sun in the sky, as reported here.

  The stacked images, constituting 24 exposures in the green filter— each lasting 35 seconds , 2 exposures in a red filter and 2 exposures in a blue filter, show a large glowing halo extending out to half a million kilometers (5 arcminutes). The images show at least 7 distinct jets, some of which are anti-tails in the sunward direction.

  At the time of observations, 3I/ATLAS was 7–10 degrees above the horizon. Eventually, twilight interfered with the observations, which took place under a bright moonlight. Is the network of jets associated with pockets of ice on the surface of a natural cometary nucleus or are they coming from a set of jet thrusters used for navigation of a spacecraft? We do not know. For now, let us enjoy the view. After all, a picture is worth a thousand words.
