The SkyMapper Southern Sky Survey, which seeks the most metal-poor stars in the Galaxy, has identified 122 low-metallicity stars in the Galactic halo and obtained high-resolution spectra for them.

Lithium was detected in spectra of nova V1369 Cen. Based on this observation, calculations suggest that classical novae could be one of the major Lithium producers on a Galactic scale.

Simulations of the convective motions in solar prominences suggest that cool, dense chromospheric material is mixed into the prominence matter and carried to large heights.

The collision of stars with jets emitted from the centers of nearby active galaxies may create a detectable non-thermal radiation signature.

17 giant stars from the Kepler survey are reported to exhibit rapid rotation, with periods of 13 to 55 days — much faster than the values predicted by stellar evolutionary theory.

This is the release of the deepest source catalog ever in the 100MeV-300GeV range! It includes over 3000 gamma-ray sources, of which more than 1000 are identified as blazars.
