homeland The American “NASA” agency for space research revealed the first five full-color images and spectral data from the most powerful space telescope in the world, the James Webb Space Telescope, for one of the famous cosmic galaxies, which is about 500 light-years away from Earth.
James Webb, the world’s most powerful telescope
The latest images come about two weeks after the telescope sent the deepest and clearest infrared image of the distant universe to date.
The James Webb telescope is the most powerful telescope in the world and was jointly manufactured by space agencies in Europe, the United States and Canada.
The US Aeronautics and Space Agency (USA)NASA) On its official account on “Twitter” that the James Webb Space Telescope, a partnership with the European Space Agency ESA, sent a new image of the “Kart Well” galaxy, which is about 500 light years from Earth.
Time to reinvent the wheel.
Here’s the Cartwheel Galaxy in a whole new light — as a composite image from 2 instruments on the Webb telescope. Webb uniquely offers not just a snapshot of the galaxy’s current state, but also a peek into its past & future: https://t.co/QdXPwAwwac pic.twitter.com/SJD3wTxwRP

The galaxy consists of two rings, a luminous inner ring containing a huge amount of hot dust and a colorful ring surrounding it. NASA said this image shows that the galaxy is in a very transitional phase and will continue to transform.
Mystery surrounds the galaxy Kart Well
The statement said that other telescopes, including the Hubble Space Telescope, have previously observed the Kart Weil galaxy.
The statement added: “However, the exciting galaxy is surrounded by mystery, perhaps due to the amount of dust that obscures the observation process.”
According to the source, NASA’s “James Webb” space telescope revealed new details about the formation of stars and the central black hole of the galaxy.
And by infrared, it was possible to reach a detailed picture of the “Cartwheel” galaxy.
The report, extracts from which were translated by Watan, pointed out that the collision of galaxies significantly affected the shape and structure of the Cartwheel Galaxy.
The galaxy contains two rings: a bright inner ring and a colorful ring surrounding it. These two rings extend outward from the center of the collision, like ripples in a pool of water after a stone is thrown into it.
Because of these distinctive features, astronomers call it a “ring galaxy,” a structure less common than spiral galaxies such as our own Milky Way.
The dusty region between the two rings reveals numerous stars and stellar clusters.
The bright core contains a huge amount of hot dust, with the brightest regions being home to young, giant star clusters.
On the other hand, the outer ring, which spanned for about 440 million years, is dominated by star formation and supernovae. When this ring expands, it enters the surrounding gas and leads to star formation.
Despite the mystery surrounding the Cartwheel galaxy due to dust that obscures the view of it, the James Webb telescope was able, by infrared, to reveal new insights into the galaxy.
Infrared revealed regions within the Cartwheel galaxy rich in hydrocarbons and other chemical compounds, as well as silicate dust, much like dust on Earth.
Thick dust in the pulp
According to the same study, NIRCam also revealed the difference between the smooth distribution or shape of older star clusters and the dense dust in the core compared to the lumpy shapes associated with younger star clusters outside.
Webb’s observations confirm that the Kartwell galaxy was a regular spiral galaxy like the Milky Way before its collision, and while the Webb Telescope gives us a quick glimpse into the current state of the galaxy, it also provides insight into what happened to this galaxy in the past and how it will evolve in the future.
The telescope was launched on December 25, aboard a Marian rocket, from the European Space Agency’s Kourou launch pad.
The development of the James Webb telescope took about 30 years and cost about ten billion dollars, and this telescope is a successor to the Hubble telescope in use for more than thirty years.
