Now the small galaxy is also preying on the younger ones, if the remains are found, the scientists were also shocked.


Highlights

  • Astronauts discover remnants of another galaxy in a smaller galaxy
  • For the first time, evidence of a small galaxy eating a galaxy smaller than itself was found
  • Large galaxies eat away less powerful galaxies through the force of gravity

Astronomers have found a large number of interconnected stars in the Large Magellanic Cloud (LMC) of space. LMC is a small galaxy located close to our Milky Way. On investigation, it was found that all these stars are confined to a very short distance due to their gravity. Now scientists from the Netherlands Research School for Astronomy have told that this swarm is actually the remnant of a small galaxy. This swarm has been named as NGC 2005. Earlier it was believed that larger galaxies contained smaller galaxies, but now for the first time it has been found that smaller galaxies can also swallow smaller galaxies.

This swarm is 750 light years away from the center of the LMC
According to the study published in Nature Astronomy, the chemical composition of NGC 2005 is significantly different from that of 10 other globular clusters found in the Large Magellanic Cloud. This swarm of stars is located about 750 light-years from the center of the Large Magellanic Cloud. It is being told that about 200000 stars are included in this swarm. Silicon, zinc, calcium and copper are present in much smaller quantities in this herd than in the other 10 groups.

This swarm was not formed during the formation of the Galaxy
On the basis of which scientists claim that this cluster was not formed during the formation of the Galaxy. Rather, this cluster was formed by the merger of neighboring galaxies. Scientists believe that nearby smaller galaxies merged into the Large Magellanic Cloud. During this time, stars were also formed in this cluster. During the merger of the Milky Way, the smaller stars split apart, while the larger central globular cluster NGC 2005 remained. This cluster later made the Large Magellanic Cloud (LMC) its home.

Small galaxies are also swallowing small ones
Astronomer David Messari of the University of Groningen in Italy said that we have now proved for the first time that the small galaxies around our galaxy are also made of other small galaxies. Scientists already know that larger galaxies do not spare smaller galaxies. Larger galaxies have more powerful gravitational force. In such a situation, they absorb less powerful small galaxies inside themselves. But, it is now known that even smaller galaxies are capable of absorbing galaxies smaller than themselves.

LMC is 3.7 times smaller than our galaxy
According to scientists, the interesting thing is that when the merger happened, the size of the LMC was much smaller than it is today. The diameter of the LMC is 14,000 light-years, which is about 3.7 times smaller than our Milky Way galaxy. There are more than 150 known globular clusters in our galaxy, which are much older than open star clusters. The age of many of these groups has been estimated at 13.5 billion years.
