And according to the “RT” website, NASA shared the image with the inhabitants of Earth, and it reveals that the star was extruding its outer matter, and slowly building a halo of layers of gas and dust around itself.
As the ejected gas moves away from the star, it cools and forms a cloud, or “nebula,” that glows in the James Webb infrared camera. This makes the clouds pink in the image.
And those projectiles are the star that rushes to the final explosion in an event known as a supernova, and the pre-supernova stage of the star’s life is called “Wolf-Rayet”, and it is a type of very massive star where the mass of the star is greater than 20 solar masses, These stars are characterized by a large loss of mass that emerges from them in the form of a stellar wind with a speed of 2000 kilometers per second.
Some stars go through a very short “wolf-right” phase before they die, making this type of star a rare sight.
The star was called WR 124, and it is located in the constellation of Sagittarius, and its mass is 30 times the mass of the Sun. He threw in material equal to 10 suns to create the glowing nebula in the image.
This cosmic dust is of great importance to astronomers, as it is one of the elements that make up every body in the universe, such as new stars and new planets.
The new dusty material comes from old, dying stars that explode and eject it all into space, in a cosmic feat of recycling.
According to NASA, there is more dust in the universe than astronomers’ theories can explain. And James Webb can help solve the mystery by finding more clues about the origins of the dust, including supernovae and “wolf-ray” stars like this one.
The telescope’s powerful infrared capabilities make it a much better tool for studying dust than any previous observatory.
And NASA wrote in a statement accompanying the image: “Before James Webb, astronomers interested in dust did not have enough detailed information to explore questions about dust production in environments such as WR 124, and whether dust grains were large and abundant enough to survive a supernova.” and become a significant contributor to dust aggregates. Now these questions can be investigated with real data.”
