Dalla GIF originale monocromatica realizzata dall' HST ho applicato una elaborazione con l'ausilio della " palette" che permette di creare una mappatura a colori ed evidenziare le varie fasi di frammentazione della cometa 73/P S-W.

From the monochrome original GIF realized by the HST I have applied an elaboration with the aid of the " palette" that it allows to create a color map and to underline the various phases of fragmentation of the comet 73/P S-W.

In questa GIF animata realizzata il 18 aprile 2006 dal telescopio spaziale Hubble ( HST ) viene immortalato il disgregarsi del frammento B della cometa 73P/Schwassmann- Wachmann.

 In this GIF animated realized April 18 th 2006 from the spatial telescope Hubble (HST) the is immortalized to break up him some fragment B of the comet 73P/Schwassmann - Wachmann.

Elaborazione con applicata la funzione negativa inversa in cui risaltano i numerosi frammenti di varie dimensioni.


Elaboration with applied the inverse negative function in which are underlined the numerous fragments of various dimensions.

A mio avviso questa elaborazione è la più completa perchè vengono evidenziate le reazioni morfologiche e fisiche conseguenti all'evento di frammentazione della 73/P S-W.

To my notice this elaboration is the most complete because the morphological reactions and consequent physics to the event of fragmentation of the 73/P S-W are underlined.
