   THE  Dominik Riechers, an astronomer at Cornell University in      Ithaca, New York, "finding just one hyper-luminous starburst             galaxy is remarkable in itself.
       Astronomers have for the first time spotted two hyper-           luminous starburst galaxies, extremely bright and spectacularly                massive galaxies,  in the   early universe.     

Astronomers found the 2 interacting galaxies, collectively known as ADFS-27, as they began the
The study was published in the Astrophysical Journay.

Some important points


• It appear as a single red dot in the telescope's survey of the southern sky.

• The current observation of the astronomers reveals that the two galaxies are producing stars at a very high pace, about 1000 times faster than Milky Way.


• The galaxies pair is located approximately 12.7 billion light-years from Earth .(the direction of the Dorado constellation.)

*The ADFS-27 system is reported to have approximately 50 times the amount of star-forming gas as the Milky Way Galaxy.

• At this distance, astronomers viewed this system as it appear
when the universe was only about one billion years old.

 ADFS-27 discoverey

• The researcher first finds this system with the help of the European Space Agency Herschel Space Observatory.

• The initial observations suggested that the apparently faint object was in fact both extremely bright and extremely distant.

• Follow-up observations with the Atacama Path finder Experiment (APEX) telescope confirm these initial interpretations  the way for more detail of observations.

• The APEX telescope in Chile has a high resolution and greater sensitivity and due to this it able to measure the distance to the object and reveal that it was in fact 2 distinct galaxies.

According to the Astronomers
this merger may eventually form the core of an entire galaxy cluster. Galaxy clusters are among the most massive structures in the universe.
