The Universe is one of my favorite documentary,here in Brazil came out the first season box-set only,even so is better than nothing...in this episode about others galaxies explain how far they are and how many kinds and shape,today in space has three powerful telescopic among them the most famous Hubble, each one has an own field using different system to watch, also useful information about Black Holes and Quasars,all them distinctively explained by colorful graphic computer....learning such things is unforgettable experience that lives forever!!
