What is the round red/orange dot at the edge od the picture?
I'm new here, at galaxyzoo.
When you look, at this galaxy, it just look like a "normal" E3-4 elliptical galaxy, but if you look closely at the corner of the pictrue, there is this quite perfect round dot. I thought, at first glamse, that this might could be a supernova. But first of all, Elliptical galaxies mostly hace old stars, and little to no star formation. I also think it might be a little to pefectly circular to be a supernova remenent?
What do you think? Sorry if there is any mistakes, but my English is quite bad.

Hi Capella.cebine.ragn and welcome to the Zoo
This is actually a simulated galaxy from the Illustris data set. (More info here : https://blog.galaxyzoo.org/2015/09/21/new-images-for-galaxy-zoo-part-2-illustris/).
And these simulated galaxies are placed in original backgrounds. So, the red dot at the bottom is just a foreground star from our galaxy (sadly not a supernova ! )
Hope this helps and happy hunting !😄
