It’s probably not far from the truth.&nbsp; I say this because what I am about to ask, may well fit into that (ignorant) category. But since I don&#39;t know the answer, I was hoping someone could spare the time to enlighten me.&nbsp; Recently, I was staring into the Hubble ultra deep field&nbsp;photograph and noticed something interesting.&nbsp; Namely twin galaxies, or what appears to be the same galaxy in two places.&nbsp; I was wondering if this is an example of gravitational lensing?&nbsp; I would attach a picture of their locations if I could figure how to insert a bitmap file in here.&nbsp; But, failing that, I&#39;ll try to describe the location of the point 1/2 way between the two galaxies (I keep calling them galaxies; they appear to be spirals seen edgewise, but they could be anything).&nbsp; Given that the HUDF photo is square and 100 units on each side, the point ½ way between the objects is 24.5 units down from the upper left corner of the photo, and 43.3 units to the right from the upper left corner.&nbsp; The objects are separated by approximately 16.3 units. They both lie on a line almost exactly parallel with the horizontal edge of the photo.</p> <p class="MsoNormal">Possibly I am the only one on earth who does not know that this was noticed years ago when the photo was first released, or I got hold of a copy of the HUDF that had been photo shopped for a joke (funny!).<span>&nbsp; </span>Anyway, what gives here?</p>
