Astronomers found a star factory outside of our galaxy named HFLS3, which is 12.8 billion light years from Earth.
It produces the equivalent of 3,000 suns per year, making it 2,000 times more prolific than our Milky Way Galaxy.
It is so far away from our galaxy that scientists are looking back in time when they view it, as they can only see it when the universe was six percent of its current age.
The large galaxy has a giant reservoir of gas, perfect for the formation of new stars.

"This is the most detailed look into the physical properties of such a distant galaxy ever made," Dominik Riechers, of Cornell University, said.
"Getting detailed information on galaxies like this is vitally important to understanding how galaxies, as well as groups and clusters of galaxies, formed in the early universe."
It was difficult to determine the galaxy's distance form us, as it required observations with 12 different international telescope facilities with orbiting and ground-based telescopes.
Their ranges were from visible-light telescopes to telescopes that worked in infrared, milli-meter wave and radio wavelengths.

The mass of the galaxy is nearly 40 billion times the mass of the sun, and the gas and dust alone are more than 100 billion times the mass of the sun. Mysterious dark matter also envelopes it, enabling it the eventually grow into an entire cluster of galaxies.
"This galaxy is proof that very intense bursts of star formation existed only 880 million years after the Big Bang," Riechers said.
"We've gotten a valuable look at a very important epoch in the development of the first galaxies."
