interesting shape on this picture

Hi and welcome to the Zoo,
You posted this on the general Zooniverse Talk.
In the future, it is better to posts questions on the project's Talk. That way you'll get an answer sooner.

But anyway, this is an artefact called #windows_ghost.

Quote by Sandor Kruk :

This is a strange image artefact that appears in HST images, known as a "Figure-8" #windows_ghost. They are caused by reflections off the CCD detected window of a bright source that is observed by HST.

Thanks for participating and happy hunting !
