Since he started creating images, The James Webb Space Telescope has been able to peer through time and large amounts of dust. In each picture, the so-called largest and most powerful telescope ever launched into space managed to dazzle the world. Now released a new image of the Cartwheel Galaxy, also known as cart wheel galaxy It is located about 500 million light-years from Earth in the constellation Sculptor. What this photo revealed, which experts classified as “unprecedented.”
The Kartwell Wheel Galaxy, located 500 million light-years away in the Sculptor constellation, is a rare sight. Its appearance, like a spinning wheel, is the result of an intense event: a high-speed collision between a large spiral galaxy and a smaller galaxy. which are not seen in this photo,” they explained from NASA and the European Space Agency It is a statement.
In this sense, they highlighted that “Collisions of galactic proportions cause a series of different, smaller events between the respective galaxies; And Cartwheel is no exception“Because he is in the picture that was revealed.”New details about the formation of stars and the central black hole of the galaxy“.
As they pointed out This high-speed collision caused the wagon’s wheel to take its current shapebecause the effect caused the formation of dThey recounted that the rings that spread out from the center of the galaxy were “like ripples in a pond after a stone was thrown.”. The impact of the collision significantly on the shape and structure The cartwheel galaxy, which has two rings: a bright inner ring and a colorful ring surrounding it.described them.
They noted that these two rings “expand outward from the collision center,” and as a result, astronomers They called it a “ring galaxy,” a structure less common than spiral galaxies such as our own Milky Way.. “The bright core contains a huge amount of hot dust, and the brightest regions are home to giant clusters of young stars. On the other hand, the outer ring, which has been expanding about 440 million years ago, is dominated by star formation and supernovae.“, they continued. They noted, “As this ring expands, it collides with the surrounding gas and leads to star formation.”
This image is not the only one published by NASA and the European Space Agency. Is that Webb was able to capture a mid-infrared (MIRI) image, in which a “bright inner ring and an active outer ring” are observed. Although this outer ring has a lot of star formation, the dusty region in the middle reveals many stars and star clusters.
Webb’s powerful infrared look produced this detailed image of the Cartwheel and two smaller companion galaxies against the background of many other galaxies.. This image offers new insight into how the Cartwheel galaxy has changed over the course of billions of years.And they added in the message where they confirmed it These are images of “unprecedented clarity”.
In that tone, the statement highlighted that Near Infrared Camera (NIRCam)who is the chief photographer for Webb,”Observing the crucial wavelengths of light, which can reveal more stars than is observed in visible light.. This is because young stars, many of which form in the outer ring, are less opaque due to the presence of dust when seen in infrared light.”
“In this image, NIRCam data is colored blue, orange, and yellow. The galaxy shows many odd blue dots, which are individual stars or star formation hotspots.. NIRCam also reveals 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 of it.”
In addition, they note, these instruments allow them to learn finer details about the dust inhabiting the galaxy, because it “requires interpretation of the Webb’s Mid-Infrared Instrument (MIRI).” MIRI data is colored red in this composite image. It reveals regions within the Cartwheel Galaxy that are rich in hydrocarbons and other chemical compounds, as well as silicate dust, much like dust on Earth.”they added.
Finally, they highlighted itThese regions form a series of spirals that essentially form the skeleton of the galaxy. These radii are shown in earlier Hubble observations published in 2018, but are becoming more apparent in this Web image.” The latest space instruments allowed him to see “a huge amount of hot dust” that obscured the view of the galaxy.
“Webb’s observations confirm that the Cartwheel is in a very transitional stage. The galaxy, which is assumed to be a normal spiral galaxy like the Milky Way before it collided, will continue to shiftThey said from NASA and the European Space Agency; He concluded:While Webb gives us a quick glimpse into the current state of Cartwheel, he also gives insight into what happened to this galaxy in the past and how it will evolve in the future.“.
