Hubble Spots Earliest Bright Objects

[Fraser]

SUMMARY: The most recent photos released from the Hubble Space Telescope show objects so old they might be from a time when stars in the universe were just starting to shine in significant numbers - about 13 billion years ago. These objects are at the limit of Hubble's resolving power, but the next generation James Webb Space Telescope is expected to see the entire group of proto-galaxies, and look back even further.

When we look back 12 billion LYs, we should see a configuration of the universe with a much smaller radius than it has currently. In keeping with our oft used balloon analogy, we are not only looking across its ever expanding surface but also toward the equivalent of its ancient smaller surface. Do we see the expected increase in density (closer packedness) of galaxies?
