Early Galaxy Found

Astronomers have recently observed the earliest galaxy found so far. They say it formed only about 200 million years after the Big Bang.  It therefore would be among the first galaxies to form.

Researchers found it by focusing NASA's Hubble and Spitzer telescopes on a tiny area of the sky, so they believe more galaxies of that epoch are there to be disscovered.  That wouldn't necessarily jibe with current cosmological theory, which tends to put galaxy formation at a later period.
