... We present color-magnitude diagrams (CMDs) derived from HST WFPC images in the F555W and F785LP filters of the post-starburst galaxy NGC 1569 and we discuss its star formation history. ... To discuss the star formation in NGC 1569, we superpose on the CMD the whole galaxy (see Fig.1) the isochrones calculated by Fagotto et al. (1994) for Z=0.004 as appropriate, since Dufour et al. (1982) and Hunter et al. (1982) derive for NGC 1569 a metal content in between those found for the LMC and the SMC. ...

Starbursts are short-lived events, stars are forming so quickly that the reservoirs of interstellar gas from which stars are coalescing would be used up on a timescale much shorter than the age of the galaxy . ... Strong stellar winds from giant new stars in the starburst region combine with the blasts of supernovae to push a mighty flood of extremely hot gas, a ?superwind? from the galaxy thousands of light years into intergalactic space. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...
