In the year 2199, unrelenting attacks from the planet Gamilus have forced all life on Earth into underground dwellings and raised radiation levels to near-toxic levels. The only way to clean up all this harmful radiation is by using the Cosmo Cleaner, which the Queen of the planet Iscandar has generously offered to humanity. Unfortunately, Iscandar is 148,000 light years away, but Earth only has one year before rising radiation levels make it uninhabitable! The only vessel capable of making the journey is the battleship Yamato - a rusty relic of World War II. Can the crew of the Yamato make it to Iscandar and back before the extinction of all life on Earth?

I've admittedly not seen more than a few episodes of Yamato, but based on what I saw these two series have a remarkably similar feel. That's to be expected I suppose given the same person was involved in both titles. Each is an old school sci fi tale, though Yamato is more of an adventure while Blue Noah is more of an ongoing battle with aliens.
