Is Constellation 88 the star of all galaxies?

That's not true. Constellation itself contains all the stars and other celestial bodies in the Milky Way, such as star clusters, nebulae and other galaxies. But not all the stars in the galaxy can see it.

Constellations have no distance. Constellations just look at the sky from the earth and artificially divide the sky into regions. All celestial bodies located in this area belong to this constellation, no matter how far or near. It's like standing on the top of the mountain and looking in a certain direction, whether it's a river near the mountain, a field in the middle distance, or a faint town in the distance, until the mountains in the horizon are in this direction.

Therefore, even in the same constellation, the distance between each star is different, some are closer, some are farther, and some two stars seem to be close, but in fact they may be far apart. Of course, all the stars that can be seen from the earth are in the Milky Way. Because the 88 constellation includes all the sky except the earth, it includes all the space centered on the earth. But the total number of stars in the Milky Way galaxy may be as high as 200 billion. Even with the largest telescope, you can't see so many stars.

There are not only stars in the constellation, but also extragalactic galaxies, such as Andromeda galaxy, Magellanic galaxy and so on. These galaxies are not in the Milky Way, but other galaxies outside the Milky Way.

If the telescope is powerful enough, you can see almost countless galaxies in a constellation. If the Hubble Space Telescope is used to observe deep space, hundreds of galaxies can be seen in the field of view with a diameter of 0.5 degrees (about equal to the diameter of the moon).
