Artefact - or not

  • Peter_Dzwig by Peter_Dzwig

    Got this one through. Its a bit odd. Are there smaller nuclei within this, or is it my eyes? In the positive image there are definitely bluish blobs appearing. In the negative, they are less so. Could they be an artefact of the process?

    Hi Peter

    Apparently the blue blobs are star forming areas in the galaxy.

    This is from Illustris, and - as Els says - 'star-forming regions' (in the sim) tend to look like blue blobs.
