hi everyone,

We're still a long way from galaxy/qso redshifts of 20 to 30, but we're getting towards 10:

Spectroscopic confirmation of a galaxy at redshift z=8.6 Lehnert et al. http://arxiv.org/abs/1010.4312

By comparing to other high z galaxies, the stellar age is suggested to be in the range 0.01 to 0.1 Gyr.
