... 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. ...

... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...
