Discovered the merger of galaxies 13 billion years ago

Thanks to the telescope system in Chile, scientists observed the merger of the oldest galaxy in the constellation Sextans.

The Japanese team observed the signs of oxygen, carbon and dust in the galaxy B14-65666 thanks to the ALMA telescope system in Chile, Fox News reported today. This is the oldest galaxy found all three signs.

When comparing the signs, the expert group defined B14-65666 actually consists of two galaxies combined. This means that this is the oldest galaxy merger ever observed.

B14-65666 is located in the constellation Sextans. The signal from here must pass 13 billion light-years to reach Earth, according to Takuya Hashimoto, a researcher at the Japan Science Development Association and Waseda University. Therefore, scientists can observe images B14-65666 13 billion years ago, less than a billion years after the Big Bang.

"The detection of radio waves from oxygen, carbon and dust in such objects proves that ALMA has a great ability to study distant space , " Hashimoto said.

Scientists will continue to use similar studies to discover the origin of the universe . "The early universe seems to be a very interesting period for galaxies. Many violent collisions occur and are not like the orderly structures that we often see in later stages," Dan Marrone, Professor at the University of Arizona, commented.
