Hi all,
Just joined GalaxyZoo and found this image with an odd ray wich seems to join an arm of the galaxy, what can this be?

Hi lazzardo and welcome to the Zoo
I just answered your question (see left). It is a diffraction spike (optical artifact) caused by a bright star outside of this image.
Happy hunting ! 😄
