Scientists observed the formation of a supermassive black hole in a galaxy merger 8.3 billion years ago, supporting the hypothesis that such black holes can form directly from collapsing gas clouds, providing new insights into their origins.
A new study published in Astronomy & Astrophysics reveals that the weird composition of globular clusters may be the result of being baked by gigantic “monster stars” when the universe was young. These monster stars, 5,000 to 10,000 times the size of the Sun, quickly fused material into increasingly enriched matter, then spread that matter throughout the molecular cloud in a heterogeneous manner, which explains why some stars in a cluster will have significantly higher or lower concentrations of certain elements. The James Webb Space Telescope has confirmed high proportions of nitrogen in a globular cluster located 13.3 billion light-years away, which could only have been formed in the core of a supermassive star.
