The James Webb Space Telescope has begun collecting images of the universe in (infrared) light from its observing instruments. It was this time that his eyes fell on the side of the Cartwheel galaxy, providing new detailed images of this structure at a distance of 500 million light-years from us.
As a result of a collision of a spiral galaxy with another smaller galaxy, it has two expanding rings, giving it its characteristic shape, with a black hole in the center.

The Hubble telescope has already photographed this structure, but James Webb’s infrared instruments are enriching the view of this star-creating galaxy with new details.

Check out these Hubble and Webb views of the Cartwheel Galaxy! From Hubble’s perspective, the sparkling blue regions indicate the birth of stars.
Thanks to @NASAWebb’s infrared vision, which cuts through clouds of gas and dust, previously invisible stars are revealed! pic.twitter.com/xGvALIDaiG

Infrared observation, in particular, overcomes the blurring of the dust surrounding the galaxy, and two instruments, NIRCam (near infrared) and MIRI (mid-infrared), made it possible to create a composite image that defines vision (and our understanding). phenomena.
It is also a look at the evolution of the collision that happened 440 million years ago. Thus, NASA is causing the “transitional state” of the Chariot Wheel galaxy.
The image also shows two other nearby galaxies and many stars in the background in a higher level of detail than before.
