Seeing our universe in three dimensions is hard considering our vantage point

It goes without saying, the universe is a big place. There's plenty left to discover about our universe, but we know a remarkable amount of things about it considering our vantage point, a small rock orbiting a rather ordinary star towards the edge of the Milky Way.

We can see plenty of stars and galaxies in the sky, but determining their position in three dimensions, rather than the two we can see them in, is hard.

Still, there are 3D maps of portions of the universe, and one of the most recent aims to go back into the early universe and map out galaxies and galaxy clusters to determine how they evolved into the structures that exist today.

The FastSound project is using the Subaru Telescope in Hawaii to do a survey of the sky and look at a region as it was nine billion years ago.

Even back then, galaxies started to lump together, creating the filaments that we know are scattered throughout the universe and the voids between the accumulated mass.

While the map goes back to nine billion years ago, because the universe expanded during that time, the distance between us and the current location of those galaxies is larger in light years.
