The James Webb Space Telescope has revealed a stunning view of a cosmic mess

BingMag.com The <b>James</b> <b>Webb</b> <b>Space</b> <b>Telescope</b> has <b>revealed</b> a <b>stunning</b> <b>view</b> of a <b>cosmic</b> mess

NASA's James Webb Space Telescope has this time looked at the huge mess of the Cartwheel Galaxy and revealed new details about star formation and its central black hole.

Webb's powerful infrared vision produced this detailed image of the Cartwheel galaxy and two smaller companion galaxies against a background of many other galaxies. This image provides a new view of how the Chariot galaxy has changed over billions of years.

The Chariot galaxy, located 500 million light-years away in the constellation Sculptor, is a It is a rare cosmic sight. Its appearance, very similar to a wagon wheel, is the result of a violent event. A high-speed collision between a large spiral galaxy and a smaller one not visible in this image. Collisions with galactic dimensions cause a sequence of different and smaller events between the involved galaxies, and the cartwheel is no exception.

This collision has further affected the shape and structure of the galaxy. The Cartwheel Galaxy has two rings, a bright inner ring and a colorful outer ring. Like ripples in a pond after a stone is thrown into it, these two rings spread outward from the center of impact. Because of these distinctive features, astronomers call it a "ring galaxy," a structure less common than spiral galaxies like our Milky Way. It is home to young giant star clusters. On the other hand, the outer ring, which has expanded for about 440 million years, is dominated by star formation and supernovae. As this ring expands, it rips through the surrounding gas and causes stars to form.

Other telescopes, including the Hubble Space Telescope Before this, they had checked the wheel cart galaxy. However, this dramatic galaxy is shrouded in mystery, perhaps due to the large amount of dust obscuring its view. Now James Webb is revealing new insights into the nature of the cartwheel with its ability to detect infrared and beyond visible light. It looks at the universe as close as 0.6 to 5 micrometers and sees important wavelengths of light that allow it to show even more than stars seen in visible light. This is because young stars, many of which form in the outer ring, are less obscured by dust when viewed in infrared light.

In this image, Nirkam data are colored blue, orange, and They appear yellow. The galaxy displays many blue dots, which are individual stars or star-forming regions. NIRCAM also shows the difference between the uniform distribution, or shape, of older stellar populations and dense dust in the galactic core compared to the clumpy shape associated with younger stellar populations outside.

However, learning finer details about The dust in the galaxy requires the Web Intermediate Infrared Instrument (MIRI). Miri's data are highlighted in red in this composite image and show regions in the Cartwheel Galaxy that are rich in hydrocarbons and other chemical compounds, as well as silicate dust, similar to much of the dust on Earth.

These regions They form a series of spiral blades that essentially form the skeleton of the galaxy. These vanes were also seen in previous Hubble observations published in 2018, but they are much more prominent in this web image.

Web observations confirm that the Wheelbarrow Galaxy is in a very transient phase. The galaxy, which was probably a normal spiral galaxy like the Milky Way before the collision, will continue to change shape.

While the web, as the world's premier Space science observatory, provides a snapshot of the current state of the wheel. It gives us a cart, but it also reveals a view of what happened to this galaxy in the past and how it will evolve in the future.
