How can we know the distance between these two "blobs"?

    Apparently there are two galaxies/blobs in this image. How can we know if these galaxies or objects are near each other. Well they appear to be near each other from the image's perspective.

    Both galaxies appear distorted, so it is very possible that they are interacting. And that would mean that they are 'close' to each other.
    To be absolutely sure, you'd need additional info (redshift).

    Hope this helps ! 😄

    Happy hunting !
