Astronomers Calculate Distance of the Earliest Known Galaxy

An international group of astronomers found the earliest and most distant galaxy. The galaxy, named EGS-zx8-1, surfaced around 670 million years after the Big Bang.

Researchers from Yale University along with the experts of University of California Santa Cruz analyzed the blurry infant galaxy. They used three different high tech telescopes to measure its exact age. They calculated the shift in light segments of the galaxy.

In the end, researchers concluded that the galaxy is around 13.1 billion light-years away from Earth.  The long distance even affects its light intensity. Hence, its light is relatively faint as compared to the other distant galaxies. However, the galaxy is bright and active as its speed of formation of stars is greater than Milky Way. It contains more than 15 percent of the mass of the Milky Way.

Garth IIingworth, astronomer from the University of California Santa Cruz, revealed details of the new galaxy.  He notifies that it was certainly one of the most difficult discoveries.

In 2013, an astronomer from Yale University was studying Hubble Space Telescope images when he spotted a bright spot. Later on, he used Spitzer Space Telescope to confirm its presence. However, scientists have recently calculated its accurate distance.

Furthermore, NASA scientists intend to use NASA’s James Web Space Telescope to observe other distant galaxies.

The study is printed in the recent issue of Journal Astrophysical Letters.
