Strange, Ancient Stars of the Milky Way -Challenge Current Understanding


Globular Cluster M 80


“The discovery of this exceptional globular cluster remnant will help refine models of the formation of the first stellar structures of the Universe,” astronomer Nicolas Martin told The Daily Galaxy about the discovery of a stellar structure known as C-19 uniquely comprising stars with extremely low metallicity. Recent studies suggest that planetary systems made up of terrestrial-type planets in compact, tightly-spaced orbits are most likely to form around lower-metallicity stars. Small planetary systems orbiting low-metallicity stars have been around a lot longer, and may be the earliest type of planetary system, making them an ideal place to search for life.
