Astronomers have found "Sparky", a developing galaxy containing a dense compact core that blazes with the light from millions of newborn stars.

They explained that the infant galaxy is located very far and first appeared 11 billion years ago which was three billion years after the big bang.

Astronomers said that the compact core formation is just the start of the galaxy formation it will continue to grow until it became a giant elliptical galaxy.

Erica Nelson from Yale University said that they really hadn't seen a formation process that could create dense objects.

She explained that the core formation process is a unique phenomenon that can be found in the early universe.

Sparky is only a fraction of the size of Milky Way but contains twice as many stars than Milky Way, which is cramped in a region 6,000 light years away.

Nelson explained that Sparky has a very extreme environment where there's a lot of dust, gas and remnants of exploding stars.

Through their research, they found out that the new galaxy produces 300 stars per year, which is definitely a lot compared to Milky Way that only produces 10 stars per year.

Astronomers believe that the frenzied star formation was caused by a galactic center forming inside a gravitational dark matter well.

Upon observation, astronomers found out that the furious star formation had been happening for more than billions of years.

They believe that there was a time that the galaxy couldn't keep up with its star formation which eventually stopped forming stars in its packed core.

There might have been smaller galaxies emerging from growing galaxies causing its outward expansion for the next 10 billion years.

Pieter Van Dokkum, one of the researchers, said that their discovery settles the question whether this kind of galaxies can occur.

He said that they believe that there are still other galaxies like this that are fainter and near-infrared wavelengths, which they have to find.
