These are relatively close galaxies that face the Earth. The research reveals new details about the way galaxies are formed

A new trove of images from the James Webb Space Telescope show portraits of 19 Earth-facing spiral galaxies. They show stars, gas and dust on the smallest scales ever observed beyond our galaxy. Teams are studying these images to discover the origin of the complex structures. The collective analysis of the research community will inform the simulations of theory developers, and advance our understanding of star formation and the evolution of spiral galaxies.
If you follow each of the galaxy's well-defined, star-studded arms to their center, there can be older star clusters and sometimes active supermassive black holes. Only the James Webb Space Telescope can provide highly detailed scenes of nearby galaxies in a combination of near- and mid-infrared light, and a series of these images were released today.
These images from Webb are part of the large and ongoing PHANGS (Physics at High Angular Resolution in Nearby Galaxies) project supported by more than 150 astronomers worldwide. Before Webb photographed them, the project already had lots of data from various space and ground-based telescopes, including observations in UV, visible and radio light. Webb's near- and mid-infrared contributions provided several new parts of the complex.
Webb's upcoming InfraRed camera captured millions of stars in these images, which shimmer in shades of blue. Some of the stars are scattered throughout the spiral arm, but others are grouped together in star clusters.
The data from the telescope's mid-infrared instrument highlights luminous dust, showing us where it is behind, around and among the stars. They also shine a spotlight on stars that have not yet fully formed – they are still enveloped in the gas and dust that fuels their growth, like bright red seeds at the edges of dust peaks.
To the astonishment of astronomers, Webb's images also show large spiral envelopes of gas and dust possibly created by exploding stars.
The extensive gas regions of the spiral arms also reveal details in red and orange. Astronomers study them to find out how a galaxy distributes its gas and dust. These structures will provide important insights into how galaxies form, sustain and shut down star formation.
There is evidence that galaxies grow from the inside out - star formation begins in the heart of the galaxy and spreads along its arms, in a spiral movement from the center. The further a star is from the heart of the galaxy, the more likely it is to be relatively young. In contrast, the regions near the heart that appear illuminated by a blue spotlight are regions of ancient stars. A galactic heart bathed in pink and red diffraction edges may indicate an active supermassive black hole or saturation with bright star clusters toward the center.
Scientists can begin to explore in many directions with the combined PHANGS data, but the unprecedented number of stars Webb separated is a great starting point. In addition to the immediate release of these images, the PHANGS team also released the largest catalog to date of approximately 100,000 star clusters.

It's not strange that there are pictures of entire galaxies. throughout the universe. But there isn't one real picture of the Earth's 'globe' in full size?!
Sparrow, why are you looking for an alternative explanation for something you don't understand? First you will learn what others have already studied and then if their explanations are not good in your opinion, then you are welcome to explain where they were so wrong that a completely new (old) explanation is needed.
Imagine a printed circuit of electronics where there are many transistor components. Resistors, capacitors, jockeys ... but picture it from the back side where there are round connection points where all the legs of the components are composed. And basically you see all the routes that connect point to point.
Let's delete all the connections between point to point and just look at all these round dots that are on the printed board. (You have to remember that from the back side you can't see it, all the components are located, each and every component and its function.
Now imagine us (the zeroes in the universe) looking at the printed circuit board from its back side.
Each and every galaxy, each star has a unique role in the universe (which is equivalent to the printed board) there is one whose role is amplification, one whose role is to reduce power, one whose role is to transfer energy from one direction and the other to prevent, etc... In short, there are many different roles but we do not see their roles, we only You see the bends.
We do not see the contexts between them and the mutual effects (we only recognize very few of the effects and even that is doubtful) of one on the other.
And because we are not able to really see all the details in the universe, we actually admire the beauty and shape of these circles, stars and galaxies.
And basically let's assume that something built this printed circuit in order to have a screen on which animals and humans will see and hear and feel and live.
Just imagine that the entire universe has one function.
Earth!!!!
