View of Distant, Faint Galaxies Reveals Young Galaxy Building Blocks
Embedded in this Hubble Space Telescope image of nearby and distant galaxies are 18 young galaxies or galactic building blocks, each containing dust, gas, and a few billion stars. Each of these objects is 11 billion light-years from Earth and much smaller than today's galaxies.

Faint Blue Sub-Galactic Clumps may be Galaxies Under Construction
These 18 small blue objects - each 11 billion light-years from Earth - could be the seeds of some of today's galaxies. Each clump contains several billion stars. Astronomers believe that many of these objects have collided and merged with each other over time to grow into the giant and luminous galaxies seen around us today.
