Una galleria di fotografie di galassie del nostro Universo Locale.
Tutte le immagini sono state selezionate dall’archivio Astronomy Picture Of the Day (APOD), dalla galleria fotografica dell’European Southern Observatory (ESO) o dalla galleria fotografica del telescopio spaziale Hubble (HubbleSite): sono tutti siti Web altamente raccomandati, da esplorare in qualsiasi momento della giornata, in qualsiasi momento dell’anno – – vi potreste sentire minuscoli, e alla fine, meglio.
Cliccando sulle singole immagini si accede alla versione ad alta risoluzione (tipicamente decine di MB).
