Key to location of Galactic Building Blocks in Hubble field

The boxes in this color image identify 18 sub-galactic sized objects in a Hubble Space Telescope survey of faint galaxies.
All the boxed objects are at the same distance from Earth (11 billion light-years), and are scattered across an area of sky 2 million light-years across.
They are close enough to each other, they may eventually merge to form normal galaxies.
