Default 4,000 of the earliest galaxies in our universe mapped in 3D

4,000 of the earliest galaxies in our universe mapped in 3D


Astrophysicists have produced the largest 3D map of our universe at a time when it was in just in its infancy.

Light from distant stars and galaxies can take hundreds of millions to billions of years to reach us — depending on how far away they are — which means when we look at galaxies now we're looking back in time. This new map is a picture of what can be seen from Earth today, but takes us back to almost the very beginning of our universe.
