By analyzing spectroscopic data, astronomers have investigated the globular cluster Omega Centauri, aiming to find a population of stars with very low metallicity. The study resulted in the detection of the 11 most metal-poor ...
Using the Cerro Tololo Inter-American Observatory (CTIO), Russian astronomers have conducted a chemical study of the galactic globular cluster NGC 6652. Results of the study, presented in a paper published April 13 on arXiv.org, ...
A research team led by physicists at the University of California, Riverside, reports tiny satellite galaxies of the Milky Way can be used to test fundamental properties of "dark matter"—nonluminous material thought to ...
