Say hello to our local supercluster, Laniakea, home to more than 100,000 galaxies and stretching an estimated 500 million light years across.
In an amazing study for Nature, scientists mapped out thousands of galaxies in our local vicinity discovering that the Milky Way is part of a massive supercluster of galaxies which they named Laniakea. As you can see in the image above, the Milky Way is just a speck of dust in Laniakea. The actual size of the Milky Way is as big as the rest of the tiny dots spread over the image, not the size of the red dot.
If you were to zoom out of this image, you would see that Laniakea has a neighbouring super cluster called Perseus-Pisces.
If you zoom out even further, these neighbouring superclusters amount for a small portion of the known universe that consists of densely packed voids and superclusters. It looks something like this:
