Hi DavinaD67 and welcome to the Zoo
This is a simulated galaxy from the Illustris dataset. See here for more information on these images : https://blog.galaxyzoo.org/2015/09/21/new-images-for-galaxy-zoo-part-2-illustris/
And in these images blue (or white) dots or smudges signify star forming areas in the galaxy.
Happy huntng ! 😄
