  The WMAP satellite has provided a new measurement of the age of the Universe,
of $13.7 \pm 0.2$ Gyr. A comparison of this limit with constraints from stellar
evolution imply that the oldest globular clusters in the Milky Way galaxy have
a reasonable probability of have formed significantly after reionization. At
the same time, one can derive a direct {\it upper limit} on the time after the
big bang before globular clusters in our galaxies formed of $\approx 3$ Gyr,
which significantly reduces our uncertainty since before the CMB age estimate.
The WMAP age constraint can also be shown to provide a stringent {\it lower
bound} on the equation of state of dark energy. A precise value of this lower
bound would require a global analysis of the WMAP parameter constraints.
However, making conservative assumptions about allowed parameter ranges and
correlations one derives a lower bound of $ w > -1.22$. Combining this with the
WMAP-quoted upper limit on $w$ thus gives roughly symmetric 95% confidence
range $w =-1 \pm 0.22$.
