A familiar face for a distant galaxy?

A galaxy that became a spiral galaxy when the universe was less than 
10% of its current age!

Galactic Building Blocks Found?

Galaxy formation has been a puzzle.

Some thing galaxies formed from the bottom up.  The hubble space telescope
has revealed the missing galaxy pieces.

    The AAS found tiny nests of star formation.  The building
blocks we've been looking for.  Both 1/30 the size of the Milky Way.
12billion light years away, they are primordial star clumps from which
the present day structures like the milky way were formed.

The object 53W002 began the excitement.  The farther away
an object is the faster it recedes and the more its light
spectrum is redshifted since the universe is expanding.
(it's redshift is 2.4 = 12bil. lt years away).  The 18 objects
formed a cluster spread across 1 million lt-years of space.
Each being 1500lt years across.  Its just the size that
gravity could overcome thermal pressure in the gases left over
from the big bang, drawing them together to form the pieces that
later assembled into full sized galaxies.  The clumps have a 
blue tint, the result of UV radiation redshifted into the 
visible spectrum.  This is marker of hot short lived
stars, so the clumps are sites of vigorous star formation
as expected for pieces of embryonic galaxy.

Do Galaxies Fly through the Universe in Formation?

Quantized redshifts.  Astronomers found redshifts are restricted
to particular values so galaxies tend to move in clumps.
