即使在超大质量黑洞附近，恒星也能丰富星际介质

天文学家发现，演化阶段的渐近支巨星能够向星际介质中贡献物质。韦布空间望远镜的最新观测表明，这一过程甚至可以在超大质量黑洞附近发生，尽管那里的强辐射可能会摧毁分子。

Astronomers know that evolved AGB stars shed their outer layers, contributing to the makeup of the interstellar medium. But new JWST observations show this can happen even near a supermassive black hole, where powerful radiation could obliterate molecules.
