The Magnetism in Massive Stars (MiMeS) project is a statistical survey to answer the big questions related to magnetism in hot, massive stars. So far they have observed 166 stars, 14 of which host strong, ordered magnetic fields.
Astronomers have discovered an extremely metal-poor, low mass star located in the Galactic Halo. SDSS J102915+172927 appears to have fewer metals than ever predicted for stars of this mass since many models of star formation suggest that a star with these properties should not have even formed in the early universe.
