NASA — Meet "Sparky."
That's the name astronomers have given this incredible discovery in the farthest reaches of space.
You're looking at a new image of what's called a galaxy construction -- seen by the Hubble and Spitzer space telescopes, as well as observatories on the ground.
Scientists say this is a dense collection of millions of rapidly-forming stars.
The galaxy construction is so far away that the light we're seeing in this photo took eleven-billion years to reach Earth.
Astronomers say the cluster will give new insight into how stars, galaxies, and the entire universe formed.
