This photo, taken by the Hubble Space Telescope, is called the eXtreme Deep Field (XDF) and it is the deepest view of our universe that has ever been taken.

This one image took a whopping 500 hours to develop, as the Hubble “stared” at this particular point for about 22 days.

NASA elaborates further on its webpage, saying, “The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.”
