A theoretical model of the cluster lens is used to "unsmear" the
gravitationally-lensed image back into the galaxy's normal appearance.
The corrected image gives a highly magnified view of the distant galaxy
with detail 5-10 times smaller than Hubble alone can provide. It clearly shows
several bright, very compact regions of intense star formation.
These
starburst regions are as 700 light-years across. The knots are so bright they
indicate bursts of star formation taking place at a much faster rate than seen
in most galaxies at the present time.
