NASA's Hubble and Spitzer space telescopes have helped the astronomers observe the earliest stages of enormous galaxy construction. They have named this young, massive galaxy as Sparky. It has been termed as GOODS-N-774.

The observations of the Hubble Space Telescope, Herschel Space Observatory and the Spitzer orbiting satellite were combined with the data collected from the ground by astronomers at Keck Observatory in Hawaii.

The data states that Sparky is located 11 billion light years from Earth and is a fully developed elliptical galaxy, a structure that is poor in interstellar gases that fill other forms of galaxies. Further, considering the fact that the galactic core of the galaxy is so far away and studying the light of this forming galaxy from Earth, it has been concluded that Sparky was actually created 11 billion years ago, just 3 billion years after the Big Bang.

The size of this galaxy is believed to be only a fraction of the size of the Milky Way. Although the tiny powerhouse galactic core of Sparky contains about twice as many stars as our galaxy, these stars are crammed into a region only 6,000 light-years across. This is very less in comparison to the Milky Way that is about 100,000 light-years across.

A study led by Erica Nelson of Yale University has delved into the inner workings of this huge, early galaxy. Nelson and her team observed that the galaxy was extremely massive and was still undergoing formation of its core. Also, clouds of gas orbiting the galactic core were faster than any galactic cores ever measured.

Nelson said, "We really hadn't seen a formation process that could create things that are this dense. We suspect that this core-formation process is a phenomenon unique to the early universe as it was more compact. Today, the universe is so diffuse that it cannot create such objects anymore".
