The Ring Nebula, formed by a star shedding its outer layers, is a classic example of a planetary nebula and is also relatively close to us.

The James Webb Space Telescope observed the famous Ring Nebula in unprecedented detail. The Ring Nebula, formed by a star shedding its outer layers, is a classic example of a planetary nebula. She is also called M57 andNGC 6720, and is relatively close to Earth, about 2,500 light years away.
The new images have unprecedented spatial resolution and spectral sensitivity, which also reveal unique details in the two AA observations. For example, the new image from the Nearest AA Camera shows the intricate details of the filament structure of the inner ring, and the new image from the Intermediate AA instrument reveals specific details in the concentric shapes in the outer regions of the nebula's ring.
There are about 20,000 dense globules in the nebula, which are rich in molecular hydrogen. In contrast, the inner region shows very hot gas. The main shell contains a thin ring of enhanced emission from carbon-based molecules called polycyclic aromatic hydrocarbons. About ten concentric arcs are just beyond the outer edge of the main ring. The origin of the rainbows is thought to be in the interaction between the central star and a companion with a small mass that orbits at a distance similar to the distance between Earth and the dwarf planet Pluto. In this way, nebulae like the Ring Nebula reveal a kind of astronomical archaeology, and astronomers study the nebula to learn about the star that created it.
The shape of the nebula resembles a twisted doughnut. We are looking almost directly down one of the poles of this structure, with a barrel of brightly colored material moving away from us. The center of this donut may appear empty, but it is actually filled with less dense matter that moves both closer and further away from us, creating a shape similar to a rugby ball that is embedded within the donut's central gap.
The main ring consists of gas ejected by a dying star at the center of the nebula. This star is on its way to becoming a white dwarf - a very hot, dense and small body which is the final stage of development of a star like the Sun.
The Ring Nebula is one of the most prominent objects in our sky. It was discovered in 1779 by the astronomers Antoine Dracier de Paipois and Charles Messier, and added to the Messier catalog. The two astronomers encountered the nebula when they were trying to follow the path of a comet through the Nebula group, which passed very close to the Ring Nebula.
These observations were made as part of the GO 1558 observing program of the James Webb Space Telescope.

I'm really shocked Kathy I will think
It's a huge thing in size... but I wonder... would we see the whole sky beautiful blue at night if the earth was in there? Or because of the size, we will hardly notice colors, shades and shapes?
What's more... if we were about 70 thousand light years from the Andromeda galaxy, then at night half of the sky would be the galaxy and the billions of stars in front of our eyes... a sight so beautiful that it cannot be produced even in Hollywood
For us it is an eternal distance.
