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.

These calculations suggest Kepler-discovered planets circling binary star systems on ~1AU orbits likely didn’t form in situ, but instead formed further out and migrated in to where they are now.

An abnormally high-velocity RR Lyrae star near the Galactic bulge might be a Galactic halo interloper. This suggests additional halo contamination might exist in the bulge RR Lyrae sample.
