90 some galaxies and many thousands of nebulae studied in the report. Explosive star formation observations? The observations of *star formation* in these galaxies are not the same as dark star formation or Population III stars in BB cosmology. These stars (assumes they existed) *evolved* in a very different universe, very different size and very different CMBR temperature as well as no dust grains for star formation.
The report by space.com features some very good galaxy images. NGC 4303 is a good example, M61.
