MOTHRA向我们展示了螺旋星云中恒星的物质循环

天文学家利用位于智利的MOTHRA望远镜观测了著名的螺旋星云。研究发现，垂死恒星喷射的碎片与星际气体碰撞产生了激波，揭示了恒星物质如何回归星际介质以孕育新生星与行星。

Astronomers used new MOTHRA telescope in Chile to image the famous Helix Nebula. They found 22 glowing shock waves where stellar debris from a dying star collided with interstellar gas. After colliding with gas, stellar fragments remain intact for just 10,000 years, the team estimates. The observations show how dying stars are recycled and return material to the interstellar medium to form new stars and planets.
