Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

These are likely active galaxies feeding supermassive central black holes and large clusters of galaxies at distances of up to 12 billion light-years. The stunning picture supports astronomers' ideas of a youthful universe in which massive black holes were much more dominant than at present.
