Astronomers have discovered two galaxies that merged 1,280 million years ago. They claim that if the two galaxies merge, a giant galaxy will be formed. The new giant galaxy will be one of the brightest objects in the universe. They said that this event is very important to understand the early evolution of galaxies and black holes in the universe.

Yoshiki Matsuoka of Japan's Ehime University discovered these two galaxies with the Subaru Telescope. Astronomers then analyzed data from the new galaxies using the Atacama Large Millimeter or Submillimeter Array radio telescope. They tried to know about the quasar through telescope data.
Quasars are luminous cosmic objects, powered by matter falling into supermassive black holes at the center of galaxies in the early universe. According to the theory, when two gas-rich galaxies merge, a single massive galaxy is formed. A variety of quasar activity can be detected when gas falls into a supermassive black hole in the gravitational interaction of two galaxies.
According to astronomers, the galaxies in the constellation Virgo were separated by 900 million years from the beginning of the universe. Both galaxies are currently very faint, indicating that the quasars are still in the early stages of their evolution. Radio telescope observations suggest that the quasar's host galaxy is connected by a bridge of gas and dust. This suggests that the two galaxies are in fact merging.
The telescope shows gas in two galaxies. Quasar activity will be seen here on a large scale in the future. In addition, mergers will lead to rapid growth in star formation. Scientists call this event a starburst. Giant galaxies will develop due to starburst activity and the strong presence of quasars.
