Abnormality?

by Solan
This galaxy appears like a typical spiral galaxy at first glance, but when I switched the lighting, I noticed the tiniest sliver of what appears to be matter drifting from the galaxy to another place a little bit below and to the left of said galaxy. Is this some sort of abnormality? Or a possible black hole sucking matter from the galaxy?

Hi @Solan,
Welcome 😃
I am not so sure what you mean about switching the light? Do you mean inverting the image?
Look forward to hearing back from you!

Which I always find very interesting especially if they are present in different surveys, but usually they are artifacts / removed artifacts / change pixel alignments etc. etc. This one also looks faintly present in DECaLS and SDSS both.
Here are some more examples in a thread I now and then update out of curiosity;
