0067-0057 te indeed to have the ability to look back in time and observe galaxies as they were billions of years ago. Perhaos in no other discipline is it possible to gain such a direct view to hJstory. The galaxies we seek to study are remote, their light faint, and thus only recently has it become technicaJ

Age and Processes of Star Formation in Very Young LMC Associationsanic Cloud (LMC);30 Dor and the neighboring regions. Coherent results were obtained for a burst of star formation and for a decreasing rate. A constant star formation is not consistent with observational data.

M Giants in the Galactic Nuclear Bulgevery reddest of the M giants may be connected with the metallicity gradient. When these M giants are added on to some models, the resulting integrated infrared colors reproduce the observed colors of spheroidal systems quite well.

IZW18 and the Search for Very Metal Poor Galaxieslong quiescent periods would meet the requirements and the age of the galaxies can be normal. On the other hand these objects can be genuinely young namely undergo their first burst of star formation. The debate is not yet closed and I propose here to add a bit by speculating about the rarety of objects like IZW18.

Bolometric Luminosity EvolutionIRAS-selected galaxies, and IRAS source counts, indicate that there may indeed exist a rare population of galaxies with such high star formation rates. The most luminous found so far approach quasars in luminosity.
