Is the light bending around some gravitational point, or is that an* artifact of the telescope itself? If the former, that is astounding. Edit: nvm I think I figured it out myself. There are objects next to smeared galaxies that are not distorted. The distorted objects must be behind the gravitational field, and the un-distorted objects in front.

  Seems to be multiple objects creating gravitational lensing. I assume that is what's causing the weird smudged galaxy.

  They said the bending isn't an artifact of the telescope.

  It looks like there are undistorted galaxies right next to the distorted ones, overlapping even. That suggests it’s not just a telescope artifact.
- dougmwne 4y ago
  It is a gravitational lens. A massive concentration of matter in between us and the galaxies behind it that bends the light and give us an extra magnification factor. Strange to look at, they can also boost the light gathering ability of the telescope and give us valuable information about the very early universe.

Is each of those spirals really the size of our whole galaxy? And if we were to zoom in 100x more, would there be just as many galaxies to see, or is there a perceivable outer edge to our universe's expansion?
- dougmwne 4y ago
  That and more. Currently we think there are 2 trillion of those little dots in the observable universe. There have been some very interesting whole sky surveys that have mapped many of them. The Sloan Digital Sky Survey has data on location, distance and spectroscopy on 50 million of the little buggers. They have some neat 3D maps, think milk being stirred into the black coffee of the vast.
  - peter303 4y ago
    I read the count of "observed" galaxies is 170 billion, i.e. extrapolating the deep field count. Certain assumptions about faint and redshifted galaxies increases that number to about trillion. Early galaxies may not look as regular and spirally as recent galaxies. JWST will see more detail in the early universe to better quantify this.
    - dougmwne 4y ago
      Yes, if we were to take our best image ever, the Hubble eXtreme Deep Field and multiply it by the whole sky, we would likely see 176 billion galaxies using that same telescope and exposure. That could be considered a lower limit. But we also have models of mass and galaxy formation that suggest the number of galaxies within the observable universe is many times larger, maybe up to 2 trillion. Hubble cannot see everything at every wavelength, even if we have unobstructed line of sight to it.
- dougmwne 4y ago
  And to answer the questions you edited in, yes, there is an edge to the universe. It is the literal edge of time, the moment when everything was one and infinite (a singularity, we think). This edge is 13.8 billion light years in every direction. As we look far away and back in time, we can see the whole history of everything, from just after the universe cooled and expanded enough to be transparent to light, to the first protogalaxies and all the development of everything up until our very noses.
