The latest image, processed by an international team of astronomers from NASA’s James Webb Space Telescope (JWST), contains the sharpest image ever of the Messier 57 nebula. This gives astronomers new details and fascination regarding the future of the Sun. The Ring Nebula (called M57 by astronomers) is a spiraling gas cloud nebula 2,300 light-years from Earth, best visible from Earth in August. M57, a nebula formed by the implosion of a dying star roughly the size of our Sun regarding 20,000 years ago, is of growing interest to scientists. The study of M57 will allow scientists to predict the future of the Sun, as it expands similarly over the next few billion years. Unlike other nebulae, M57 is tilted, allowing scientists to see little-known physical processes going on inside. The chemical reactions taking place in M57 are spectacular, as indicated by the emitted colors, and gaseous components seen in the images include clouds of helium, nitrogen, oxygen, hydrogen and sulfur, as well as traces of large carbonaceous molecules. be. M57 is an easy object to spot, and amateur astronomers can see its characteristic donut ring throughout the summer. The James Webb Space Telescope is entering its second year of operation, and the gorgeous imagery from the $10 billion project does not disappoint. Equipped with a series of infrared cameras and a sunshield, the Webb telescope can see objects nearly nine times fainter than its 33-year-old predecessor, the Hubble telescope. We have been sending images since July 2022, and have provided many wallpaper-worthy photos that capture a corner of future life. To mark its one-year anniversary, NASA last month released images of 50 new stars born in the closest star-forming regions to Earth. M57 is expected to be an amazing place for both life and death. As with many nebulae, gas exhaled by dying stars ends up in interstellar clouds. When this gas and dust mixture becomes heavy enough, it collapses under its own gravity and then new stars are formed. The images come amid renewed interest in stars and space. India’s historic lunar mission Chandrayaan 3 launched last month, and Japan’s JAXA plans to launch its X-ray Spectroscopy and Imaging Satellite (XRISM) and Small Lunar Lander Demonstration Vehicle (SLIM) on August 26. . Meanwhile, at the Kennedy Space Center, NASA completed its first Artemis 2 recovery test two days ago. Artemis 2 will be the second of three missions to reestablish the US lunar presence. And the U.S. government is expected to allocate $27.2 billion to NASA in next year’s budget proposal. (original forbes.com)
