This image, taken with the NASA/ESA Hubble Space Telescope, shows one of three images of the same very distant galaxy whose light has taken 13 billion years to reach us. The galaxy has been magnified and multiply imaged by the lensing effect of the galaxy cluster Abell 2744. By measuring the angular separations between the three magnified images of the galaxy a team of astronomers were able to further constrain their measurement of the galaxy’s distance from Earth. Much like using your camera to focus on an object, and then reading its distance from you on the lens focus ring. This makes this possibly the most reliable distance measurement yet of an object that existed in the Universe’s formative years.
