New image of the Ring Nebula from the James Webb Telescope. The universe creates beautiful things for us to look at and study it endlessly, such as the Ring Nebula, discovered in 1764 by French astronomer Charles Messier. This object was given the alternate name Messier 57 (M57). It has become the focus of both amateur astronomers and expert astronomers alike. Even the Hubble Space Telescope has studied it many times. But thanks to the infrared power of the James Webb Space Telescope (JWST), we can see things we’ve never seen before. as we can see in this picture “We always knew that planetary nebulae were beautiful. But what we see now is very beautiful,” said Albert Zijlstra, professor of astrophysics at the University of Manchester. Planetary nebulae are found throughout our Galaxy and vary in shape. Some are like glowing rings. Some are structured like soap bubbles. The Ring Nebula resembles a jelly donut. Despite being called a planetary nebula, But it has nothing to do with planets. The reason why it got this name was because in the past People who see it often mistake it for a planet. Due to its beautiful round shape, it is like a planet. but in fact it is The “death of a star” similar to our Sun “We are witnessing the final chapter of a star’s life. It foreshadows the distant future of the sun. And JWST observations have opened a new window to understanding this awe-inspiring cosmic event,” said Mike Barlow, principal scientist for the Ring Nebula project. Astronomers believe that This nebula was a former sun-sized star that began ejecting its outer layers about 4,000 years ago. It grew into a red giant and then shed its outer layers into space to form an expanding cloud. out at a speed of about 20 kilometers per second These colors and structures tell a fascinating story about stellar evolution. It has provided many scientific insights. Scientists detect heavy elements forming during the lifetime of a dead star But eventually it can pass on life to new stars. Much of this matter is clumped together into enormous clouds of gas and dust known as galaxies. They form ‘Interstellar Clouds’ as they condense under their own gravity. It will continue to produce new stars. “By studying the Ring Nebula with JWST, we hope to gain a deeper understanding of the life cycles of stars and the elements they emit into the universe,” said project scientist Nick Cox. one person said The Ring Nebula is about 2,000 light-years from Earth in the direction of the constellation Harp. (Constellation Lyra) can be seen with conventional telescopes. Retrieved and edited by Vitit BoromphichaichatkulPhotograph Courtesy by JWST/University of Manchester Source: nebula
