Astronomers developed a mosaic of the distant Universe -- called the Hubble Legacy Field -- that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains nearly 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. Image credit: NASA / ESA / G. Illingworth & D.
