Himiko and Orochi, giant galaxies first discovered by a Japanese astronomer, are receiving lots of international attention. Himiko is located 13 billion light years away from earth and is the oldest galaxy ever discovered, and Orochi is fifty times the size of our Milky Way. Viewers will be dazzled with a striking animation of a galaxy collision, the same kind as would have given birth to these two giants. This episode unmasks these two cosmic bodies and the potential they have to rewrite our galactic evolutionary history. What did the giant galaxies that existed at the dawn of the universe look like? What fate awaits the Milky Way as it slowly moves on its 7-billion-year collision course, with the Andromeda Galaxy?
