    i'm new here and it just showed me this photo.
    Does someone know what those blue dots are?

    Hi roobbex and welcome to the Zoo

    The blue dots are actually artifacts. They are cosmic ray hits that didn't get removed from the image. But they stil look very cool though ! 😉

    Happy hunting.
