There are Candles images, which look similiar to some of the "fake" AGN images from the Hubble Zoo.: I wonder, why not the whole image/galaxy looks pixelated? ???

This image from the Hubble Space Telescope CANDELS survey highlights the most distant galaxy in the universe with a measured distance, dubbed z8_GND_5296. The galaxy's red color alerted astronomers that it was likely extremely far away, and thus seen at an early time after the Big Bang. A team of astronomers led by Steven Finkelstein of The University of Texas at Austin measured the exact distance using the W. M. Keck Observatory's Keck I telescope with the new MOSFIRE instrument. They found that this galaxy is seen at about 700 million years after the Big Bang, when the universe was just 5% of its current age of 13.8 billion years
