A few preliminary remarks

1. This is not an extensive review of astronomy, but rather a collection of a few astronomical subjects that I have (subjectively...) found interesting. The number of chapters is constrained by the length of this class (4 days).



2. Bear in mind that the material presented here is only a support for the 4 days astronomy class (corso di astronomia durante la "settimana di approfondimento") that I give at the end of March at my highschool (Liceo di Lugano 2). The oral explanations that flesh out this collection of pretty pictures is, at the moment, not included. I hope they will be for a future edition of the class.



3. Each figure is accompanied by a Figure Caption (bottom left of each picture), where the Credits are mentionned. The source web-page from which the pictures were taken is also mentionned at the end of the caption. For most cases, this source web-page contains pictures, movies or animations at various resolutions and formats.



4. These pages are best viewed with a Mac OS X Safari or a Mozilla Firefox browser and at a screen size of 1024 x 768. Do not attempt to view large movies directly over the net, but rather download them onto your computer and view them separately with the quicktime player (or some other appropriate player).
