... Up: Archives and Information Services . ... The VLT Archive System goals can be summarized as follows: i) record the history of VLT observations in the long term; ii) provide a research tool - make the Science Archive another VLT instrument; iii) help VLT operations to be predictable by providing traceability of instrument performance; iv) support observation preparation and analysis. ... Figure 2: Overview of the VLT Science Archive Research Environment. ... Figure 3 illustrates the general concept...

Subsystemsof RR Lyrae Variable Stars in Our Galaxy . ... Field stars displaying more rapid motion and clusters with redderh orizontal branches constitute the spheroidal subsystem of the accreted outer halo, which is approximately a factor of three larger in size than the first two subsystems. ... Both the clusters and field stars belong to at least three Galactic subsystems: the thick disk and genetically related inner proto-disk halo, and the outer accreted halo. ...

Rep ort by the ESA-ESO Working Group on Galactic p opulations, chemistry and dynamics Abstract Between the early 40s, when Baade showed the first evidence for the existence of two distinct stellar populations, and today, with our Galaxy surprising us with new substructures discovered almost on a monthly basis, it is clear that a remarkable progress has been achieved in our understanding of the Galaxy, of its structure and stellar populations, and of its chemical and dynamical signatures. Yet, some questions

... They discovered that Ptolemy's predictions of planetary movement (based on the so-called "wrong" geocentric theory) were in fact MORE ACCURATE than Copernicus'. ... I should also point out that Copernicus did not eliminate the epicycles from his heliocentric cosmos. ... He copied Ptolemy's theory and system almost exactly, with the exception of removing the equant point. Incidentally, it was Copernicus' denial of an equant point that destroyed the veracity of his predictions. ...
