CTOnews.com, August 6 (Xinhua)-- NASA's James Webb Space Telescope (JWST) has recently brought us an amazing astronomical spectacle-a new perspective of the Ring Nebula (Ring Nebula). The annular nebula, located about 2600 light-years from Earth in the constellation Lyra constellation, is a remnant of the mass released by a dying star. This image reveals details never seen before in the nebula, giving us a deeper understanding of the formation and evolution of star and planetary systems.

The annular nebula is a planetary nebula (planetary nebula), which does not mean it is related to planets, but is named after its circular structure that French astronomer Charles Messier mistakenly thought it was a planet when it was discovered in 1764. A planetary nebula is a complex structure formed by a white dwarf star (white dwarf) throwing out its outer gas when it dies, including glowing rings and expanding gas clouds. The radiation of white dwarfs interacts with elements that have been released, giving them different colors. Each chemical element produces a specific color, allowing astronomers to study the evolution of stars.

JWST, the most advanced space telescope, was successfully launched on December 25, 2021 and began to observe the universe in June 2022. It uses infrared light to observe celestial bodies, which can penetrate cosmic dust and reveal the stars and planets hidden in it. JWST can also observe extremely distant and faint celestial bodies, exploring the earliest history of the universe.

JWST's observations of the annular nebula are led by a team of physicists and astronomers from University College London (University College London) and the University of Western Ontario (Western University) in Canada, who say JWST provides us with an unprecedented view of the annular nebula. These high-resolution images show not only the intricate details of the nebula's shell, but also the inner region around the central white dwarf with amazing clarity. They believe that we are witnessing the last chapter of the life of a star, a preview of the distant future of the sun, and that JWST observations open a new window for us to understand these awesome cosmic events.

CTOnews.com noted that JWST's observations of the annular nebula have been published in the journal Nature Astronomy (Nature Astronomy) and the images have been published on the NASA website.
