Complex images like the one of galaxy M101 allow astronomers to see how configurations in one part of the spectrum match those seen in other parts
Last week, NASA published an image composed of different parts of the spectrum and in which the vane galaxy (M101) looks like a children's toy in a cellophane wrapper. This beautiful image combines infrared, visible, ultraviolet and X-ray data from four NASA orbiting telescopes. It's like viewing an image taken with a regular camera, an ultraviolet camera, night vision goggles and an x-ray all at the same time.
Yet within the multispectral view, both old and young stars can be seen scattered along M101's wound spiral arms. Complex images like this allow astronomers to see how configurations in one part of the spectrum match those seen in other parts.
The Pinwheel Galaxy is in the Ursa Major (or Ursa Major) group. It is 70% larger than our Milky Way, and its diameter is 170 thousand light years. It is 21 million light years from Earth. This means that the light we see left the galaxy 21 million years ago – many millions of years before humans walked the Earth.

It was stated in the article that the diameter of the pinwheel galaxy is 170,000 light years and since the diameter of the Milky Way galaxy is 100,000 light years then the diameter is 1.7 times and from this it follows that the volume is 1.7 times the third which is almost five times.
And as for the age of the stars, new stars are constantly being formed - young ones, from the gas clouds inside the galaxy. The fact that there are also old stars shows that the galaxy is old.

1. When you state that the vane galaxy is five times larger than the Milky Way, what do you mean?
Physical size? Mass? Maybe both?
2. To your knowledge, what is the explanation for the fact that along the arms of the galaxy, stars are scattered in confusion
Young and old stars?
The vane galaxy is almost five times larger than the Milky Way. Seventy percent is relative to locomotives.
And besides don't forget that on Wednesday early in the morning there is the transit of Venus that will pass as a small ball over the surface of the sun.
Those who are too lazy to wake up will have another chance in a little over a hundred years (:))
good day everybody

I'm not sure it has changed much, 21 million years is the blink of an eye compared to the lifespan of a galaxy.
It's a shame that the article is not proofread:
Old and young stars...
The light we see in the place of shepherds...
As a matter of fact, a somewhat weak article without new revelations.
If so, she has already changed completely 😉
