Mystery of Milky Way G-Objects

For decades, we thought the center of the Milky Way was a binary world—populated either by robust, bright-blue "S-stars" or by delicate clouds of hydrogen and helium gas. But a discovery by UCLA astronomers has revealed a third, far more mysterious class of inhabitants: the G-objects. These "crimson ghosts" are rewriting our understanding of how stars live and die in the most extreme environment in the galaxy.

The center of our galaxy is a "stellar megalopolis" where the density of stars is one billion times higher than in our own solar neighborhood. In this crowded, chaotic space, G-objects may not be flukes, but a common end-product of life in the gravity-well of a supermassive black hole.
