This is what the universe looks like.
After the Big Bang, things aren't uniform. There are clumps here and there. Things kind of string out here, drizzle out there, smash into one another.
Two big pieces form. Each has a sort of dense backbone made up of billions of galaxies, from which filaments of hundreds of millions of galaxies stand out like hair on your head after being rubbed with a balloon.
Scientists have long known of the one "supercluster" of galaxies, and called it Perseus-Pisces. But the shape of the other has just been identified. It is known as Laniakea, a Hawaiian word meaning "immense heaven".
And where are we? In the yellow-on-black image, we're the little red dot.
