How many billions or years are the beautiful stars in the universe from the earth?
I'm sorry for my lack of knowledge. Looking up at the starry sky for ten years, I have never heard the word "beautiful stars all over the sky", and Baidu search has no clue. Obviously, this is not a universal astronomical term. When you think about it carefully, it seems that spherical celestial bodies, no matter stars, planets, etc., are hard to be associated with the adjective full of beautiful things.

In order to retrieve the memory, we must say that the celestial body associated with the adjective full of beautiful things is NGC4755 jewel box cluster:

This group of colorful celestial bodies, together, are like colorful jewelry boxes, worthy of the word exquisite. By the way, its distance is about 6500 light years.

In addition, the most commonly used unit to describe the distance between celestial bodies is light years, which means that light travels for one year. In addition, a single star must be the closest to the solar system, and the distance will generally not exceed 2000 light years. Celestial bodies in the Milky Way, such as star clusters, are no more than 30,000 light years away. Hundreds of millions of light-years away, even a galaxy as big as the Milky Way is just a dim light spot.
