Hello,
I did not realized that there are alot of people that do not know what Star Blazers is (well the TV show came out over 30 years ago). So instead of dooing a poor explanation, I will give you a link for a very good website that will explain all that is Star Blazers.

You have to see the TV show series. It was not a little kids show, great story, it was released 3 years before Star Wars. You can order them from various sites, you can even rent them at Blockbuster (online).
