We generally think of the Andromeda galaxy as It is a neighboring galaxy that lives next to us, closest to our Milky Way galaxy. But even though Andromeda is our neighbor However, it is not in orbit around the Milky Way. In fact There are dozens of neighboring galaxies or satellite galaxies orbiting the Milky Way. Of course, these are much closer to us than Andromeda.

Neighboring galaxies or satellite galaxies, such as the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC), have become areas of study for astronomers. recently Astronomers from NASA, USA reveal the use of the Hubble Space Telescope. It is a collaborative device of NASA and the European Space Agency. Look at the Large Magellanic Cloud galaxy Located 162,000 light years away, it is easily visible to the naked eye from the Southern Hemisphere under dark sky conditions and away from light pollution. They have discovered a dense population of stars, called “globular clusters” named NGC 1841, which astronomers say might provide insight into the formation of stars in the galaxy’s early days.

The reason for this is because this type of cluster has a certain consistency, i.e. it is very stable and maintains its shape for a long time. This means that globular clusters are generally very old. There are many old stars. The globular clusters look similar to fossils or fossils in the sky. And the Large Magellanic Cloud galaxy is a good place to study. Because it is the location of many globular clusters.
