Astronomers have put together the largest and most comprehensive “history book“ of galaxies into one single image, using 16 years’ worth of observations from NASA’s Hubble Space Telescope. The deep-sky mosaic, created from nearly 7,500 individual exposures, provides a wide portrait of the distant universe, containing 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the big bang. The faintest and farthest galaxies are just one ten-billionth the brightness
