The photo appears to show a plume of some kind of material on one side, along with emissions  off the opposite side. 

Cue Harvard scientist, Avi Loeb.. he believes these images of the  mysterious interstellar object named 3I/ATLAS could be additional evidence of  a type of jet engine or propulsion system on board an alien spacecraft.  In recent weeks, the object has captivated scientists’ attentions and peoples’ imaginations on what exactly this thing moving through our solar system is.

And as new imagery has become available, Loeb continues to express concern that this object, which should near Earth in mid-December, may not be a comet but rather an alien spacecraft instead.

In his blog on Medium, with new imagery in hand, Loeb writes, “The image shows two anti-tail jets out to 10 arcminutes towards the Sun accompanied by a longer collimated jet, extending away from the Sun out to an angular separation of 30 arcminutes, roughly the diameter of the Sun or the Moon. At the current distance of 3I/ATLAS from Earth, 326 million kilometers, these angular extents correspond to spatial sizes of 0.95 million kilometers for the sunward anti-tail jets and 2.85 million kilometers for the tail jet away from the Sun. This enormous spatial scale is three orders of magnitude larger than the scale of the glowing halo around 3I/ATLAS in the Hubble Space Telescope image from July 21, 2025.”..
