Can we see the stars outside the galaxy?

If you look at the sky in the dark dark night with naked eyes, everything you see except 4 or 5 planets are all stars of our galaxy. If you are lucky then you can see Andromeda Mandakini in Devromani constellation which is also known as M31 (Messier 31) Galaxy.

In the picture below, you can see Andromeda Mandakini on the arrow sign. This photo has been taken by an amateur constellation not with a telescope but by putting a camera on the tripod.

Andromeda galaxy is our nearest Mandakini and it is about 2.5 million light-years away from us. When we can see this galaxy very hard with naked eyes, then it becomes clear that it is very difficult to see the star of any other galaxy outside our own galaxy.

The farthest star we can see with naked eyes is Rho Cassiopeiae, which is only 8,000 light-years away from us. It is possible to see it because it is about 5 lakh times brighter than the Sun. It is a so-called yellow hyper joint star.

8,000 light-years is a huge distance in itself, but if we think at the level of our galaxy, then this distance is negligible. Our solar system is about 30,000 kilometers from the center of the galaxy. Whatever is in the distance of 8,000 light-years in any direction from the solar system is within our galaxy.

This is why we cannot see stars outside the galaxy without a large telescope.

We can see a lot with the help of a large telescope. The farthest possible star SDSS J1229 + 1122 we can see from the telescope is a blue super joint star that can be seen in the tail of a dwarf galaxy. We still do not have authentic information about the nature of this star. It may be a cluster or cluster of stars or something, but it is certain that it is outside our galaxy.

But there are also some stars which are located among the galaxies. Their number is very less. There are also globular clusters that orbit the galaxies. It seems that they are outside the galaxies, but many astronomers believe that they are part of the technical galaxies.

Apart from this, there are also two satellite galaxies of our galaxy which are called Magellanic Clouds. Both of these galaxies are outside our galaxy. We cannot see the stars in them, but we can see the collective dim light of those stars. The stars of the Mejlenic Clouds can also be seen without a large telescope. With a small telescope or good quality binoculars, we can also see its stars, nebula (gas clouds) and globular clusters in the middle.
