Observational survey reveals an abundance of blue faint galaxies, suggesting accelerated star formation in early cosmic epochs.

To establish automated techniques for measuring the colors and brightness of a complete sample of faint galaxies.
Conducted photographic surface photometry in two wavebands across two high-latitude fields of approximately 1080 square arcminutes each, surveying approximately 20,000 galaxies.
Calibrated photometric zero points using photoelectric stellar measurements acquired from the same astronomical fields.
Achieved sample completeness down to a flux limit roughly 10 times fainter than prior systematic galaxy investigations.
Observed that the galaxy population becomes systematically bluer at fainter magnitudes.
Detected a steep increase in galaxy number counts as faintness increases within the blue waveband.

Richard G. Kron (1980) studied this question.
