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.
