B A circle in the Hubble Ultra Deep Field picture?

  1. Nov 13, 2015 #1
    I was analyzing the Hubble Ultra Deep field image and I realized that if you look at the image from a certain distance from your monitor, you can notice there is a ring of galaxies, forming a circle. The following are the HUDF image and an image where I try to show where I see the circle (it is not properly placed, as the red line crosses some galaxies that are part of the circle, but you can get the idea).

    My question is: Can this have any meaning at all? What's the explanation for this? Can it possibly have something to do with the expansion of the universe or the Big Bang? (probably not, but anyway, I want to ask.) Cheers.

    The images are too large. Anyway, try to look at them from a distance. Tip: You can go to the article about the Universe on Wikipedia. There is a smaller image there, and the circle is more easily seen

    I think you are seeing a pattern in random data, this is quite a well known phenomena, in a sense our brain is a pattern seeking apparatus.
    There is only a strong correlation to your circle for a group of galaxies at the top, and a few weaker ones elsewhere.
    Think about it, what other possible mechanism could exist which makes different galaxies appear to form a ring as seen from Earth?
    Seen from any other perspective these galaxies would not appear as a ring, or any other recognisable shape,
    because they are not all at the same distance from us.
    Surely you are not proposing that the ring you see indicates that Earth is in a very special location in the Universe from which the ring is visible?,
    (... implying an intelligence that can engineer things on the scale of galaxies is trying to communicate with Earthlings?)
