What are the recurring blue dots all over the galaxy?

    I am new here. Could anyone shed light on the blue dots? I would imagine that they are too big to be stars. Is that normal?

    Hi AarikS and welcome to the Zoo

    The blue dots are active star forming areas in this simulated galaxy from the Illustris data set.

    Hope this helps and happy hunting !
